Description Dirkjan Ochtman (RETIRED) gentoo-dev

libffi-3.0.8 currently comes with this warning:

 * Please unset USE flag libffi in sys-devel/gcc. There is no
 * file collision but your package might link to wrong library.

It might be nice if it'd only show that if I actually have libffi set (for gcc).

Reproducible: Always

There's no sane way to depend upon sys-devel/gcc USE flags because it's slotted and you can switch between with gcc-config.

`has_version sys-devel/gcc[libffi]` would return true only if any version of sys-devel/gcc is installed with "libffi" USE flag enabled.

+  28 Sep 2009; Samuli Suominen <ssuominen@gentoo.org> libffi-3.0.8.ebuild:
+  Use has_version to print warning only if sys-devel/gcc is built with USE
+  libffi. This can be made a blocking atom once sparc is done with
+  gnustep-base/gnustep-base and old versions are removed from tree. Thanks
+  to Dirkjan Ochtman and Arfrever Frehtes Taifersar Arahesis in bug 286733.

Half-fix.

Leaving this open, waiting for sparc.

base/package.use.mask has sys-devel/gcc[libffi] masked now, and the useless warning is gone.
