Bootstrap failure in stage1 fix-header, !HAVE_DESIGNATED_INITIALIZERS

Recent CVS dies in stage1 whenever one uses cc to bootstrap on
mips-sgi-irix6.2 and sparc-sun-solaris2.7. Fix-header gobbles up
memory until it runs out and xmalloc fails.
The trigger appears to be the HAVE_DESIGNATED_INITIALIZERS else-clause
since if I force the compiler to take the else path, it always fails
even with gcc. The following patch is enough to trigger the problem
on the above two platforms with gcc for stage1, and as well on
x86-linux if you make stmp-fixproto.
If you need more help reproducing the problem, let me know.
Would you please take a look?
Thanks,
--Kaveh
