[vlc-devel] [RFC][PATCH 1/2] contrib: check os x gcc v4.2 before overriding

[Faustino E. Osuna]

Check to see if the supplied CC and CCX compilers are compatible with
GCC version 4.2. If it is not compatible, then override them with
their explicit 4.2 counterparts (gcc-4.2 and g++-4.2 respectively).

In Xcode 4.2.1, the default compilers are no longer GCC 4.2, this
should compensate for that behavior and allow older versions of Xcode
to safely be used.
