OK, I built the 64-bit and fat libgcc and then turned to the testsuite,  
expecting many failures, but there were less than I had thought. This  
apart from problems with stabs and dwarf-2 debug info, that I ignored  
for now (not reproducing "can't find atom for N_GSYM stabs ..." in the  
results below). In fact, I believe that some of the testsuite is wrong  
in a situation where Integer and Longint are both 64-bit and CInteger  
is 32-bit, as on powerpc-apple-darwin-8 when using -m64 to create  
64-bit binaries.

Some of the failures (not all) are reproduced below, with my comments.  
One possible fix of the testsuite is to replace Integer by CInteger  
where appropriate.

Adriaan van Os
