Hmm ... I did not find an entry for the path to the ld binary. I already put 
the binutils path in front of /usr/ccs/bin but gcc still uses Sun ld. Here is 
my specs file; what shall I change?

BTW: where do I find a description/specification for the specs file? I 
searched the info pages but could not find anything other than the 
description of the '-specs' command line switch.
