The following code fragments from src/libc/crt0/crt0.S are "guilty" in 
that:  lines 48-66 and 295-301 (in current CVS version)

The related structure is registrated (__register_frame_info) and as 
result the corresponding definitions from djgpp.djl are not used.

The problem is that all should work also without these things in 
crt0.S (when I did these my tests I mentioned before it didn't work 
as I expected)
