[PATCH] Shared libs on Alpha/Linux

[Erik Lindahl]

This small patch enables shared library support when using the 
Compaq compilers on Alpha/Linux. It's actually extremely simple,
just add the correct flags when we use a non-gcc compiler
on Alpha/Linux - the Compaq one is the only alternative!

NB: The dependency tracking on Alpha/Linux has just been
fixed in automake-cvs.

I'll be happy to change stuff, but do cc my adress :-)

Regards,

Erik
