Seeing as how I haven't uploaded 2.67 yet (any day now, once my upload key privileges are in place...), I took the time to run the testsuite on cygwin. I had to kill a hang in one of the parallel tests, since cygwin named fifos still misbehave in cygwin 1.7.5, but that's not autoconf's problem (we document it in BUGS, at any rate). But there were also a couple of new, unexpected failures.
253: AC_LANG_SOURCE example FAILED (compile.at:191) 254: AC_LANG_PROGRAM example FAILED (compile.at:232) It turns out that this line (in both tests): gcc -E -dD -o - conftest.c || AS_EXIT([77]) is not portable to cygwin, where gcc currently compiles ./-.exe rather than outputting to stdout. Do we really need the '-o -' in that command line? And should I be reporting the surprising behavior of creating -.exe as a gcc/cygwin bug to the appropriate folks? -- Eric Blake ebl...@redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
