RE: M4 tests fail when built with PGI compilers

Thanks Paul,

I tried applying your patch, and it looks like I got a bit further along, but 
`make check` still crashes with:

  CC       test-stddef.o
PGC-S-0045-Illegal field size 
PGC-S-0045-Illegal field size 
PGC/x86-64 Linux 16.5-0: compilation completed with severe errors
make[5]: *** [test-stddef.o] Error 2

Lines 45 and 46 of test-stddef.c look like:

      /* Solaris 10 has a bug where offsetof is under-parenthesized, and
      cannot be used as an arbitrary expression.  However, since it is
      unlikely to bite real code, we ignore that short-coming.  */
       /* verify (sizeof offsetof (struct d, e) == sizeof (size_t)); */
45   verify (sizeof (offsetof (struct d, e)) == sizeof (size_t));
46   verify (offsetof (struct d, e) < -1); /* Must be unsigned.  */
       verify (offsetof (struct d, f) == 1);

Is this expected?

P.S. I submitted a ticket to PGI regarding the bogus warning messages you 
mentioned: http://www.pgroup.com/userforum/viewtopic.php?p=21440#21440

Your log file says all the M4 tests passed; see the line "All checks
successful". The tests that failed are all Gnulib tests that do not
suggest any problems in M4 proper, only problems in the Gnulib test
harness (plus one portability bug in Gnulib that M4 should not trigger).
So you should be OK.

The Gnulib 'make check' failures are fixed by the patch I mentioned
earlier, which should appear in the next version of GNU M4. Here it is
