malloc is broken, as is calloc. Inspection indicates realloc too.
Bruno, I suggest this patch series to fix the fallout from:
http://lists.gnu.org/archive/html/bug-gnulib/2010-06/msg00176.html
I have confirmed that the tests expose the breakage of malloc and calloc
on AIX, and the final patch fixes them. OK to commit?
The patch series makes M4's own testsuite pass, but in the meantime,
something else broke again so I'm still not completely done.
Thanks,
Ralf
