test-open: port to cygwin, which lacks Fortify On cygwin, with gcc 4.8.3, I get this compilation warning: In file included from ../../gltests/test-open.c:35:0: ../../gltests/test-open.h:35:1: warning: always_inline function might not be inlinable [-Wattributes] test_open (int (*func) (char const *, int, ...), bool print) ^ On that platform, there are no Fortify enhancements, and the internal macro __always_inline is always defined to turn on the gcc attribute, contrary to our needs. Since relying on a __ prefix is already risky, it's better to limit the workaround of commit d6ba92ea to just glibc. * tests/test-open.h (ALWAYS_INLINE): New macro. (__always_inline): Don't abuse internal symbol on non-glibc. Signed-off-by: Eric Blake <eblake@redhat.com>
