Hi, autoconf.texi says that the third argument of AC_TRY_RUN (action-if-false) can use $?. This is untrue; $? gets smashed by echo and cat. autoconf 2.49d seems to introduce $ac_status to hold the pre-smashed value of $?. It'd be nice if the documentation could get fixed to reflect this before the 2.50 release. I spent a long time debugging a script that didn't work as expected under autoconf 2.13 because I assumed the documentation was correct. Thanks, Bill
