New patches from Ioannis E. VENETIS to allow building more up-to-date Alpha x-compilers.
Some patches are still missing, though.

     1 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
     2 	This trivial patch causes gcc to emit a warning whenever
     3 	it generates a trampoline.  These are otherwise hard to
     4 	locate.  It is rigged to default ON - to have it default
     5 	to OFF remove the text 'Init(1)' from the common.opt
     6 	patch, leaving just 'Common Var(warn_trampolines)'.
