-# PGAC_CLASS_STRING
-# -----------------
-# Look for class `string'. First look for the <string> header. If this
-# is found a <string> header then it's probably safe to assume that
-# class string exists.  If not, check to make sure that <string.h>
-# defines class `string'.

-# ----------------------
-# Check whether the C++ compiler understands `using namespace std'.
-#
-# Note 1: On at least some compilers, it will not work until you've
-# included a header that mentions namespace std. Thus, include the
-# usual suspects before trying it.
-#
-# Note 2: This test does not actually reveal whether the C++ compiler
-# properly understands namespaces in all generality. (GNU C++ 2.8.1
-# is one that doesn't.) However, we don't care.
