Do I need to compile gcc with some special config arguments? > Is there a library that I need to add to the command line? You'd need to build gcc with soft-float multilibs. I'm not sure that this can be supported at all on a GNU/Linux i386 system; I think you'd have to have a soft-float version of glibc, for example. Though not impossible, this would be difficult and pointless. Andrew.
