-There is one usage in boehm-gc/os_dep.c, but it is only used if
-SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or
-FREEBSD is defined, which are all not using Linux-based glibc ports.
-
-Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for
-__FreeBSD__.
-
-config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and
-config/s390/linux-unwind.h also uses a constant.
-
-I tested the following patch for sh-linux-gnu. This only covers one
-configuration, but the change is pretty mechanic anyway and every place
-that used to refer to struct siginfo already must have had <signal.h> in
-its include path, which is the same file that declares siginfo_t.
-
-OK to commit? This should probably also go into any active release
-branches, to keep them buildable once this glibc change ripples through?

- 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.
