RE: I want to build a library rather than an executable

[Adam Stein <adam at scan dot mc dot xerox dot com>]

I've never had any luck using gcc to create a shared library.  It never seemed 
to work for me (maybe I was just doing it wrong).  Using ld has always worked 
fine.  This has always been on Solaris.  I use gcc/g++ for linking a standalone 
program linking to the shared library and that takes care of libstdc++ and 
libgcc.
