GMP on IA64-HPUX

[FX Coudert]

Hi all,

Below is the answer I got from the developer of GMP when I asked about 
support for ia64-hpux.

So, it looks like we will not have gfortran on ia64-hpux before a long 
time, unless someone who cares about it enough patches the GMP sources.
Steve, how did you hack gmp to get it run?

In the short term, that also means that we don't have to care about 
supporting __float80 in gfortran ;-)

PS: I'm amazed that a "GNU project" can have exactly two developers, 
release source snapshots every two years, adopt the too common attitude 
of "every non-i686-linux platform is not mainstream", and so on.
