gcc bug fix update

Updated gcc packages that fix various bugs are now available.

The gcc packages include C, C++, Java, Fortran 77, Objective C, and Ada 95
GNU compilers and the related support libraries.

The updated packages fix several bugs including:

* g++4 could generate type-punning warnings when STL headers were used.

* complex numbers were not expanding properly using the g77 compiler
without optimization flags.

* occasionally elements shuffled in the wrong direction by the sdl deque or
erase functions. Resulting in an extra call to the assignment
operator causing deque corruption.

* the French version of g++ did not correctly handle static pointers cast
to constant pointers.

* standard encoding traits (std enc_traits) now generate a correct size
argument.

* on x86, optimization flags caused the store motion to incorrectly
compile.

All users of gcc should upgrade to these updated packages, which contain
backported patches to resolve these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
