[Bug bootstrap/42343] New: gcc 3.2.x fails to build with current gcc versions

["bero at arklinux dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When trying to build gcc 3.2.3 (or gcc-3_2-branch) with a less outdated version
of gcc [unfortunately, this is sometimes necessary to build a matching compiler
for an embedded device...], gcc barfs on the use of trigraphs as lvalues.

I'm attaching patches to fix this; chances are it's too late to get them info
the 3.2 branch, but maybe the report (and patches) will help others running
into this.
