Sorry, that previous answer was hasty and unhelpful.  gcc by default
builds 32 bit objects but the linking stage is trying to link to
OmniOS's 64 bit libraries.  I couldn't find any documentation of the
--enable-64bit flag (so I can't tell what it's supposed to do) but -m64
tells gcc to output for 64 bit, whatever other ideas it might have.  As
I mentioned previously, you need it, to ensure that when ld comes to
link all together, it doesn't have objects of unequal word sizes.  I
hope that's clear.

Michael.
