Please find the port of the patch to the new pari tree attached.
Some part are merged in the CVS.

Darwin man pages are available at 
<http://www.freebsd.org/cgi/man.cgi>
Choose 'Darwin 1.3 PPC' in the system menu.

The current issues:
1) I do not know what is the equivalent of runpath. This is likely
to make 'make bench' report BUG for the gp-dyn binary even if it
performs correctly after make install. Maybe make bench will succeed
after 'make install'.

2) Darwin use version.dylib instead of so.version. Unfortunately
the current Makefile system have no support for such naming scheme.

3) It is not clear whether the options are for gcc or ld. I suspect
my patch to do the wrong thing, but since I cannot test, I have not
changed that.

4) I do not know what are the *correct* options to build a shared
library.

5) It is not clear whether gp2c-run will work correctly.

Cheers,
Bill.
