2016-10-09	Use unnamed POSIX semaphores, if available, on Linux and FreeBSD.	Tom Lane
	We've had support for using unnamed POSIX semaphores instead of System V semaphores for quite some time, but it was not used by default on any platform. Since many systems have rather small limits on the number of SysV semaphores allowed, it seems desirable to switch to POSIX semaphores where they're available and don't create performance or kernel resource problems. Experimentation by me shows that unnamed POSIX semaphores are at least as good as SysV semaphores on Linux, and we previously had a report from Maksym Sobolyev that FreeBSD is significantly worse with SysV semaphores than POSIX ones. So adjust those two platforms to use unnamed POSIX semaphores, if configure can find the necessary library functions. If this goes well, we may switch other platforms as well, but it would be advisable to test them individually first. It's not currently contemplated that we'd encourage users to select a semaphore API for themselves, but anyone who wants to experiment can add PREFERRED_SEMAPHORES=UNNAMED_POSIX (or NAMED_POSIX, or SYSV) to their configure command line to do so. I also tweaked configure to report which API it's selected, mainly so that we can tell that from buildfarm reports. I did not touch the user documentation's discussion about semaphores; that will need some adjustment once the dust settles. Discussion: <8536.1475704230@sss.pgh.pa.us>
2012-10-11	Remove _FORTIFY_SOURCE	Peter Eisentraut
	Apparently, on some glibc versions this causes warnings when optimization is not enabled. Altogether, there appear to be too many incompatibilities surrounding this.
2012-09-30	Disable _FORTIFY_SOURCE with ICC	Peter Eisentraut
	There are apparently some incompatibilities, per buildfarm.
2012-09-29	Add _FORTIFY_SOURCE to default compiler options for linux template	Peter Eisentraut
	Many distributors use this, so we might as well see the warnings as well.
2010-09-20	Remove cvs keywords from all files.	Magnus Hagander

2008-10-29	Support for Sun Studio compiler on Linux	Peter Eisentraut
	This basically takes some build system code that was previously labeled "Solaris" and ties it to the compiler rather than the operating system. Author: Julius Stroffek <Julius.Stroffek@Sun.COM>
2007-09-21	If we're gonna provide an --enable-profiling configure option, surely	Tom Lane
	it ought to know that you need -DLINUX_PROFILE on Linux.
2006-12-12	Allow augmenting CPPFLAGS from the configure command line. This generally	Peter Eisentraut
	works, but some platform templates overwrote it without asking.
2006-03-11	Add CVS tag lines to files that were lacking them.	Bruce Momjian

2004-12-02	Don't bother adding to cflags/cppflags, just set them because configure	Bruce Momjian
	handles that, and make solaris debug use no optimization.
2004-11-27	Add to CPPFLAGS/CFLAGS in template files, don't over-ride them.	Bruce Momjian

2004-04-26	Unconditionally define:	Bruce Momjian
	-D_REENTRANT -D_THREAD_SAFE -D_POSIX_PTHREAD_SEMANTICS for all ports. It can't hurt if they are not supported, but it makes our job easier for porting. Should fix Darwin compile and other platforms without mucking with the thread detection code.
2004-04-23	Add new auto-detection of thread flags.	Bruce Momjian
	Allow additional thread flags to be added via port templates. Change thread flag names to PTHREAD_CFLAGS and PTHREAD_LIBS to match new configure script.
2004-03-14	Mark linux as thread-enabled with new 7.5 tests.	Bruce Momjian

2004-02-11	Check and set thread-safe functions separately, rather than as a single	Bruce Momjian
	variable. Remove thread locking for non-thread-safe functions, instead throw a compile error. Platforms will have to re-run tools/thread to record their thread safety.
2003-10-09	Remove -pipe on Linux, per reports from Peter.	Bruce Momjian

2003-10-09	Add -pipe compile for Linux.	Bruce Momjian

2003-10-09	This centralizes the optimization defaults into configure.in, rather	Bruce Momjian
	than having CFLAGS= in the template files. It uses -O2 for gcc (generated by autoconf), and -O for non-gcc, unless the template overrides it.
2003-09-27	Mark Linux for threads.	Bruce Momjian

2003-09-27	Finalize configuration of thread_test program.	Bruce Momjian

2003-09-27	Rename thread compile flag. Move thread test program to tools/thread,	Bruce Momjian
	and improve tests.
2003-09-26	Move -D_GNU_SOURCE hack from port header to template, so that	Tom Lane
	configure's tests see the same compilation environment as the code. Per discussion with Stephan Szabo.
2003-09-13	Attempt threading in this order:	Bruce Momjian
	* use non-_r function names if they are all thread-safe (NEED_REENTRANT_FUNCS=no) * use _r functions if they exist (configure test) do our own locking and copying of non-threadsafe functions New to this patch is the last option.
2003-09-03	Tighten casting of function call pointers for threads.	Bruce Momjian

2003-08-16	Make NEED_REENTRANT_FUNC_NAMES _require_ *_r functions, and add tests to	Bruce Momjian
	configure to report if they are not found.
2003-06-14	Move thread os defines into template files.	Bruce Momjian

2002-03-21	Remove -mips2 flag, which breaks the build on some MIPS systems.	Peter Eisentraut
	Report from Ryan Murray via Debian
2000-10-21	Move DLSUFFIX, AROPT, and CFLAGS_SL settings from template to	Peter Eisentraut
	Makefile.port, since they are of no use to configure and much of the library magic happens in Makefile.port anyway. Use __alpha, not __alpha__, since the former is universally available. Remove -DNOFIXADE from the compile command line and put it in the port include file.
2000-09-29	New unified regression test driver, test/regress makefile cleanup,	Peter Eisentraut
	add "check" and "installcheck" targets, straighten out make variable naming of host_os, host_cpu, etc.
2000-07-15	Rename templates to match names in makefiles/Makefile.* and include/port.	Peter Eisentraut
	Read templates after compiler is detected. Convert all templates to real shell scripts. Rename bsd->openbsd, alpha->osf.
1998-06-12	template changes	Bruce Momjian

1997-04-16	Fix a problem with Linux where yacc is really bison -y	Marc G. Fournier

1997-04-11	Change BACKEND to CFLAGS	Marc G. Fournier

1997-04-04	Move YACC and YFLAGS into the template files	Marc G. Fournier
	Clean up the .sample files...comment out all sample entries except for the localhost one
1997-04-04	Got AROPT setting backwards...correct it	Marc G. Fournier

1997-04-04	One helluva mess.	Marc G. Fournier
	Further extended Makefile.global/build/configure so that we can have a 'template' file for each OS (and each version of OS, as in BSDi) which is used as much as possible to generate Makefile.global Any future ports should look at using the template file as a basis, before moving over to Makefile.global. This will most probably break alot of the ports, atho I've tried to be very neat about it...
