PATCH: Fix PR 14356

[Mark Mitchell <mark at codesourcery dot com>]

My change to make GCC issue errors about modifications to const
variables broke the Cygwin bootstrap -- because there was buggy code
in gcc.c!

This patch should fix it.  Committed as obvious on the 3.4 branch and
on the mainline.
