gfortran binaries on gfortran.com: trunk now built on newer platform

[Manfred Schwarb]

Hi,

since some weeks, trunk now needs isl-0.12 to build
with graphite support. As the platform used for building
the i686 and x86_64 binaries on gfortran.com has only
isl-0.11 installed, I decided to migrate trunk builds
(and 4.10/5 snapshot builds) to a newer base (and only these).
It's a Opensuse 11.4 installation with cloog-0.18.1, gmp-5.1.3,
isl-0.12.2, mpc-1.0.2 and mpfr-3.1.2.
This means you need glibc 2.11 or newer to run these binaries.
In terms of enterprise distributions, this means you need
RHEL 6 or SLES 11, to name two popular distros. Older enterprise
distributions (i.e. RHEL 5 or SLES 10) already were somewhat
crippled under the old setting, so I hope this minimum requirement
is tolerable.

Additionally, I uploaded an installation script (gfortran-fetch-and-install.sh)
which might help some people to get these binaries more easily.
Feedback and improvements are welcome, of course!

Cheers,
Manfred
