Subject: manywarnings: update for GCC 4.8.0
X-Git-Tag: v0.1~127
X-Git-Url: http://erislabs.org.uk/gitweb/?a=commitdiff_plain;h=564705d7d91357cfbe0057f0f27a66fd8a30f0bc;p=gnulib.git

manywarnings: update for GCC 4.8.0

* m4/manywarnings.m4 (gl_MANYWARN_ALL_GCC):
Add -Waggressive-loop-optimizations, -Wreturn-local-addr, which
are new to GCC 4.8.  Remove -Wformat=2, -Wmissing-format-attribute,
-Wmissing-noreturn, as they are duplicates of other warnings.
Remove -Wunreachable-code, as it is removed in GCC 4.8 and
was documented to be flaky in earlier versions of GCC.
