Subject: Let AC_TRY_RUN be more verbose
X-Git-Tag: autoconf-2.50~410
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cf0baa2fa612ddb801c3612a0cf82e06b1203eec;p=thirdparty%2Fautoconf.git

Let AC_TRY_RUN be more verbose
* acgeneral.m4 (_AC_RUN_IFELSE): Instead of canceling the output
of the test program, save it into the log.
Save the exit status, and report it in the log when non zero.
Just use `(./conftest)' instead of `(./conftest; exit)'.
