From 182964c5f6ca39f42f5225bc76f48a185eda04b8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Attempt at detecting 64bit compilation flags between gcc, old, and new versions of sun cc
Gcc accepts -m64, just as newer version of Suncc.
Older Suncc required -xarch=v9 (SPARC) or -xarch=amd64 (x86-64) to generate 64bit code.
