Remove obsolete ifdefs

Commit 8dace66e0735ca39b779922d02c24ea2686e6521 added #ifdefs for a
number of errno symbols because they were not present on Windows.
Later, commit 125ad539a275db5ab8f4647828b80a16d02eabd2 added
replacement #defines for some of those symbols.  So some of the
changes from the first commit are made dead code by the second commit
and can now be removed.
