hpux is screwed

[Marc Slemko <ma...@worldgate.com>]

current code on hpux (and any other systems that require extra flags to
get an ansi compiler) will not compile at all because TestCompile doesn't
use the autoadded flags.

This has to be fixed, plus the *dl* replacements really shouldn't be
compiled in unless they try to use dso support.

Sigh.  Oh well, too bad.  You can work around it by manually specifying
the cflags.

I am out of it right now, so it would be really appreciated if I could
have a volunteer to roll the tarball...
