| This is because FSF GCC lacks the patch below on the 3.2 release branch

Sure, I would like to apply it.  I just need to sort out  the
following issue.  The patch you appended doesn't seem to be done
against gcc-3_2-branch.  In particular, the following hunks were
rejected

The problem seems to be that the lines

     #ifndef _BSD_SIZE_T_DEFINED_	/* Darwin */
     #define _BSD_SIZE_T_DEFINED_	/* Darwin */
     #ifndef _BSD_RUNE_T_DEFINED_	/* Darwin */
     #define _BSD_RUNE_T_DEFINED_	/* Darwin */

are missing from gcc-3_2-branch version of stddef.h.  Presumably they
were added on the other branches to solve some problems.  
I don't have access to a FreeBSD box, please could you or a FreeBSD folk
test a modified version of that patch against 3.2.2 and send a patch
against 3.2.2.? 

Thanks,
