hints/cygwin.sh: don't touch system symbol __STRICT_ANSI__
Adding _GNU_SOURCE, which was done much later, should give us the
GNU-ish symbols (though POSIX_C_SOURCE would be more general.)
I couldn't find the reason for this being added, but the C++
headers react badly to it:

Log Message:
-----------
porting/cpphdrcheck.t: test perl's headers with C++ compilers
t/porting/cpphdrcheck.t: fix finding config.h on windows
t/porting/cpphdrcheck.t: actually use ccflags
improve error reporting
t/porting/cpphdrcheck.t: improve error reporting
and make not finding a C++ compiler fail for now, to make it easier
to see the cases where we don't find one but expected to find one.
cpphdrcheck.t: capture -V output, and fix Intel compiler match
cpphdrcheck: test without -std too
cpphdrcheck: test even without -std found
cpphdrcheck: handle cc with arguments
also, do the test builds with ccflags, since I had some strange
results from the test builds, the test code would build without
ccflags, but not with, with errors deep within the system headers.
cpphdrcheck: support cc already being a C++ compiler
requires that the name contains "++"
