Well, AC_PATH_X calls _AC_PATH_X_DIRECT which

which does involve an AC_TRY_LINK. So I'd call this a 2.13 bug, or a
mis-design of AC_PATH_X, but in any case I prefer 2.50's behavior.
/tmp % cat configure.in nostromo 11:53
AC_INIT
AC_PATH_X
AC_OUTPUT
/tmp % autoconf --version nostromo 11:54
Autoconf version 2.13
/tmp % autoconf nostromo 11:54
/tmp % fgrep '$ac_link' configure nostromo 11:54
if { (eval echo configure:755: \"$ac_link\") 1>&5; (eval $ac_link) 2>&5; } && test -s
conftest${ac_exeext}; then
So it does link somewhere
/tmp % ./configure nostromo 11:55
creating cache ./config.cache
checking how to run the C preprocessor... cc -E
checking for X... libraries /usr/X11R6/lib, headers /usr/X11R6/include
updating cache ./config.cache
creating ./config.status
but does not look for a compiler.
