Subject: maint: the compiler is not always named gcc
X-Git-Tag: CVE-2013-5651~72
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ff38690be97088a399d3a7eab4a3b07f9194ab70;p=thirdparty%2Flibvirt.git

maint: the compiler is not always named gcc

https://bugzilla.redhat.com/show_bug.cgi?id=994589 complained that
even when using a cross-compiler not named 'gcc', the configure
output confusingly referred to gcc.

* m4/virt-compile-warnings.m4 (LIBVIRT_COMPILE_WARNINGS): Use a
more generic statement in configure output.
