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.
|
||||||
|
|
||||||
