Re: --host in Configure

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Hello,

I have made a new patch for Darwin that may work better than the previous one,
added with the recent change in the CVS.

Please try it.

Also it would be nice to add support in gp2c, but I need more info
about dlcompat.

Cheers,
Bill.
