+   This file outputs assembler source for gas-1.38.1 with the COFF patches
+   The patches for gas-1.38.1 to support COFF is on ftp.cs.umb.edu in pub/gnu 
+   No debugging is supported, due to the fact that the only debugger Plexus
+   had was adb *sigh*.
+
+   This is configured for label output default by gas as LXXX instead of
+   plexus cc/as combination requires .LXXX
