- Subject: [PATCH] Backport gettext fixes to get rid of warnings on macOS
This patch was tested to build binutils-gdb on GNU/Linux and macOS. It can be
applied to the gcc repo too, after fixing some trivial merge conflicts (someone
else will need to do it, as I don't have push access to gcc). Although I think
it is relatively low-risk, building gcc on macOS was not tested with this
patch, so if somebody that has already a macOS build can do it, it would be
appreciated.
Two fixes were committed recently to the gettext repo in order to make
gdb build warning-free on macOS. This patch backports them both:
- Make the format_arg attribute effective also in the case _INTL_REDIRECT_INLINE.

- Enable the format_arg attribute also on clang on Mac OS X.
