|

Deal with Autoconf 2.62's semantic change in m4_append.
|

* ltsugar.m4 (lt_append): Replace broken versions of
|
||||
m4_append.
|
||||
(lt_if_append_uniq): Don't require separator to be overquoted, and
|
||||
avoid broken m4_append.
|
||||
(lt_dict_add): Fix typo.
|
||||
* libtool.m4 (_LT_DECL): Don't overquote separator.

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.
|
||||
