This patch brings over a few features from MirBSD: | |||
* -fhonour-copts | |||
If this option is not given, it's warned (depending | |||
on environment variables). This is to catch errors | |||
of misbuilt packages which override CFLAGS themselves. | |||
* -Werror-maybe-reset | |||
Has the effect of -Wno-error if GCC_NO_WERROR is | |||
set and not '0', a no-operation otherwise. This is | |||
to be able to use -Werror in "make" but prevent | |||
GNU autoconf generated configure scripts from | |||
freaking out. | |||
* Make -fno-strict-aliasing and -fno-delete-null-pointer-checks | |||
the default for -O2/-Os, because they trigger gcc bugs | |||
and can delete code with security implications. | |||
This patch was authored by Thorsten Glaser <tg at mirbsd.de> | |||
with copyright assignment to the FSF in effect. | |||
