X-Git-Tag: VALGRIND_3_14_0~312
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=67a6cef2929635229b6c0e1b86135147d36f1ca2;p=thirdparty%2Fvalgrind.git

Fix the configure check whether the compiler supports compressed debug sections.
We need to actually link instead of just compile.
Fixes BZ#382256.
