Subject: configure.in (AC_EXEEXT): Work around in case it expands to nothing, as in autoconf... 
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4173be7fe59f3a20f11a1718003faf44f20d349d;p=gcc.git

configure.in (AC_EXEEXT): Work around in case it expands to nothing, as in autoconf 2.50.

* configure.in (AC_EXEEXT): Work around in case it expands to
nothing, as in autoconf 2.50.
* acinclude.m4: Likewise.
* configure: Rebuilt.
