I had the opportunity to do some testing on a SPARC machine and it turns 
out that CLN is indeed broken. However, if one configures with 
CPPFLAGS="-DNO_ASM" it works fine and passes all checks.

One thing that is sure broken are the functions in cl_low.h that use the 
_get_g1 macro. It appears like %g1 contains garbage. Googling around I 
was unable to find any useful information. Is there some SPARC expert 
who can provide insight into what's going on?
