given that the command to do the linking was:

/opt/tools/install/bin/gcc -I. -I/opt/tools/mdss/test/2.8/lib/perl5/5.8.5/sun4-sol
aris-64int/CORE -I./os/unix -I./include   -DSOLARIS2=280 -DMOD_PERL -DUSE_PERL_SSI -fno-st

I don't see how this could have happened. Its a gcc call, right? So the correct gcc
driver should have been used to do the linking automatically.. And if not, why not?
