Option -zc: Set Name Decoration for C

This option sets the name decoration for the C ( aka CDECL ) calling convention. There are two variants:
-zc[m|w]
-zcm is the default, C names are decorated with an underscore prefix. This is also the way Masm does it. The other variant, -zcw, omits the prefix altogether. This is the usual "decoration" in Unix/Linux.
