That just gives me the warning the other way around.  But if you add an
#undef alloca before the redefinition, it works.

But for AIX the alloca section needs to be "the first thing in the file",
which the altered system.h does not achieve.  Maybe the alloca section
needs to be split up.  (Only the #pragma needs to be first.)
