From: toddpw@wrs.com (Todd Whitesel)
Subject: Patch to opcodes/ppc-opc.c to avoid overnested parens in MSVC.
To: gdb@cygnus.com
Date: Mon, 27 Jul 1998 18:46:34 -0700 (PDT)
X-Mailer: ELM [version 2.4 PL24]
The C compiler in Microsoft Developer Studio 5 has a limit on nested
parentheses. Here is the patch I am using to avoid it, applied to 4.17.
The only file affected is 'opcodes/ppc-opc.c'.
