Subject: libstdc++: build testsuite with -Wabi
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f28ff1e4f1c91f46d80e26dd77917e47cdd41bbe;p=thirdparty%2Fgcc.git

libstdc++: build testsuite with -Wabi

I added this locally to check whether the PR120012 fix affects libstdc++ (it
doesn't) but it seems more generally useful to catch whether compiler
ABI changes have library impact.

libstdc++-v3/ChangeLog:

	* testsuite/lib/libstdc++.exp: Add -Wabi.
