If running Solaris, then you must be on Solaris 9,
since I have fenv.h in /usr/include on SOlaris 10,
and not on SOlaris 9.  As I pointed out, the only
testing I did on Solaris was on 10.

This is in fenv.h, and so are all the other macros
that are left undefined.  Not sure how we fix this,
other than pick up some of these defines manually.

Martin, given that you're doing the port for blastwave,
and I know they require both sparc/i386 support, how
did you get around this problem?

All the above errors are fallout of fenv.h not being
included.
