Did you set LDFLAGS to point to the prc-tools directory and set the  
first available 'ld' executable to the prc-tools 'ld'?  I would help  
more but I am using darwinports to build prc-tools (I have not  
experience with prc-tools or PalmOS) and it fails to build (partly  
because Apple gcc 4.0.1 defaults to a dynamic C++ library, so  
prebinding fails... there is an easy workaround so once I get enough  
CPU-time to rebuild it I will try poking around some more.

Awww... to my knowledge, that would be the first Haskell  
implementation for PalmOS :)  As I mentioned in a prior email, there  
is a Haskell arbitrary precision number library (BigFloat, at http:// 
bignum.sourceforge.net/).  You might adapt it for Integer and add it  
to Yhc if nothing else works.  I'm not crazy about BigFloat's  
performance, though.
