Subject: etags: work around GCC bug 114882
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=4a33793f7253e4ae5802cdd7bb4d20c8222c779d;p=emacs.git

etags: work around GCC bug 114882

* lib-src/etags.c: Ignore -Wanalyzer-use-of-uninitialized-value.
This applies to the whole source file, not just to areas where GCC
has bugs, as it was too tricky to ignore more selectively.

(cherry picked from commit ca4f0705be544986f11971bd8ee7dc30a8d444f1)
