5.1 current make buildworld fails consistently on crtstuff.c- Help?

Hey all.  I've been unsuccessful at performing a 'make buildworld' for 
the past week based on a cvsup of 5.1-current.  This is a fresh install 
as of ~10 days ago on a Dual Celeron BP-6 system, 784M RAM.  To say this 
is getting frustrating at this point is an understatement....anyone else 
seeing this problem or have a suggestion on how to resolve this?

Failed buildlog follows, have seen this consistently break in the same 
place for the past week of attempting 'make buildworld'.  Some debugging 
seems to point it's actually in the definition of 
CRT_CALL_STATIC_FUNCTION(SECTION_OP, FUNC), likely in the definition of 
one of the parameters themsevles, as removing the rest of the #defined 
macro 'function' still results in the same compile error.
