Subject: include the compiler name in the hash if the link count on the
X-Git-Tag: v2.4~1
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4ebb9a36352c6127ea76317f7a86eaad54bae076;p=thirdparty%2Fccache.git

include the compiler name in the hash if the link count on the
compiler is > 1, to cope with compilers (like the AIX one) that
changes behaviour based on argv[0].

Thanks to Nicholas Clark <nick@ccl4.org> for pointing out this problem
