------- Comment #1 from danglin at gcc dot gnu dot org  2006-01-29 23:29 -------
It appears that this problem was exposed by:

2006-01-28  Zack Weinberg  <zackw@panix.com>

        * c.opt: Add -W(no-)overlength-strings.
        * doc/invoke.texi: Document it.
        * c-opts.c (c_common_handle_option): -pedantic implies
        -Woverlength-strings, if not explicitly disabled already.
        (c_common_post_options): -Woverlength-strings defaults to off, and
        is always off for C++.
        * c-common.c (fix_string_type): Issue warning about strings longer
        than is portable only if warn_overlength_strings.  Rearrange code
        a little for clarity.
        * configure.in: Check for -Wno-overlength-strings as well before
        enabling -pedantic in stage 1.
        * Makefile.in (STRICT2_WARN): Add -Wno-overlength-strings.
        (gcc.o-warn, insn-automata.o-warn, build/gencondmd.o-warn): Delete.

These show up when MODIFY_TARGET_NAME is defined.

Confirmed.

This is a macro that I hadn't noticed before.  It seems the PA is
the only port to define it.  The driver options for it don't appear
to be documented.  It was added by Richard Kenner in 2000 at the request
of HP.  I doubt it works very well as the default target names in use
now don't allow the arbitrary addition and removal of 64 to select
between 32 and 64-bit targets.  Thus, I'm wondering whether this macro
shouldn't just be deleted.

I'll ping Steve.

Dave

The defect number was not put in the ChangeLog file but this was fixed in GCC
subversion revision 110476.  The change was to trunk/gcc/gcc.c.

Thanks.  I had worked out the same change last night.  Still wondering
if the MODIFY_TARGET_NAME define in pa.h is useful.
