It doesn't, but not for the reason you would hope. 8-) [cgd@cgda gcc-svn]$ inst/bin/gcc --version | head -1 gcc (GCC) 4.6.0 20110311 (experimental) [cgd@cgda gcc-svn]$ inst/bin/gcc -Wframe-larger-than=500 -Werror=frame-larger-than -c /tmp/x.c cc1: error: -Werror=frame-larger-than: no option -Wframe-larger-than IMO this suggestion disagrees with my reading of the usage -Werror in the manual (before or my after my recent change), and also disagrees with the warning name output by -fdiagnostics-show-option: /tmp/x.c:3:1: error: the frame size of 32 bytes is larger than 1 bytes [-Werror=frame-larger-than=] [note that this compiler is a few days old -- my assumption is that this behaviour didn't change since then, given the relative lockdown of GCC sources in prep for the 4.6 branch. Sorry if my assumption was incorrect.]
