+# --------------------
+# 01g,29jan13,h_k  replaced XXX with TODO.
+# 01f,24jul12,h_k  added e6500 CPU variant support. (WIND00333229)
+# 01f,12apr12,h_k  moved common env setting to defs.ppc.
+# 01e,13jun11,mze  add debug
+# 01d,23may11,syt  Added support for PPC465
+# 01c,12jan11,kab  Fix e500mc
+# 01b,03mar04,mil  Added support for PPC85XX.
+# 01a,04feb04,pch  Created (from make.PPC32gnu vn 01c).

+# DESCRIPTION
+# This file contains definitions and flags for the gnu tools
+# (compiler, assembler, linker etc.) to build for a generic
+# PowerPC without PPC60x hardware floating point.
+# If building for a specific processor (as a variant), 
+# defs.ppc will set its type number into PPC32VARIANT.
