So it be!

Here a patch, that can do a lot of interesting things, but not make 'make bench',
gp2c 'make check' or gp2c-run working. On the other hand, I would be only moderatly 
surprised if you end up with a working dynamic library.

(To apply it, copy this mail to a file and do
patch Configure < file in the pari (2.2.5) directory...)

Cheers,
Bill.
