 The commitlog for the x264 port says:

r305618 | linimon | 2012-10-10 00:43:05 +0200 (Wed, 10 Oct 2012) | 11 lines

Attempt to force this port to build only with gcc.  It is known to be
broken on clang.

However, setting USE_GCC=any appears to be insufficient: the too-clever
configure glop sees that clang is installed and attempts to use it
regardless.

This commit is thus a temporary measure.

Hat:            portmgr

 I'll Cc the x264 port maintainer, maybe he knows more.

 There was an issue with base gcc and vlc on i386 so I set USE_GCC=4.6+
- but you are right if clang is already built using it would be
preferred, and I just posted a call for testing for a patch that
defaults to using clang on 9.1+ also on amd64:

(you can use `Save link as' on the `Raw E-Mail' link at the top of
the message to download the patch, patch(1) should ignore the rest
of the message before the actual patch.)

 Thanx,
	Juergen
