That is probably safe, but it adds a fork to every AC_COMPILE_IFELSE. Cygwin would suffer especially. If we did use that approach, it would remain unwise to use #error in tests, because you would introduce a silent dependency on the next release of Autoconf. Older versions would produce a `configure' that works almost everywhere, but not with this compiler on IRIX. I recommend removing usage of #error from tests if portability to compilers with this flaw is important. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
