* This update resolves the segfault/ICE in gcc/c-parser.c while building natively
* gcc/gengtype.c was already updated to GCC 4.6.3 version previously in btrev43031, so no change there
* gcc/libiberty/make-relative-prefix is the stock 4.6.3 version now, as the workaround for Haiku is no longer needed
* This update is otherwise the GCC patches for upgrading 4.6.2 to 4.6.3 core/g++ applied to our sources
