Subject: PATCH to run autoconf tests with C++ compiler
Date: Fri, 22 May 2015 07:45:00 -0000 [thread overview]
Message-ID: <555EA4B1.8090706@redhat.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 466 bytes --]
My earlier patch to compile stage 1 with -std=c++98 ran into trouble on
FreeBSD, where that flag suppresses declaration of C99 library functions
like strtoull. I was surprised that configure was seeing the
declaration, but discovered that this was because configure was using
the C compiler rather than the C++ compiler. This patch changes GCC
configury to always use C++, and to use the normal AC_CHECK_DECLS for
overloaded functions.
OK for trunk?

commit fc47dba7c20126a51d28c34ac31be8c31ebd1ef5
Author: Jason Merrill <jason@redhat.com>

* configure.ac: Use C++ for all tests. Use AC_CHECK_DECLS for
strstr and basename.
* configure: Regenerate.
