Linux distribution

[silverio.di at qem.it]

In the past I've used RTEMS 4.5.0 with cygwin tool.
New snapshot release cooming without cygwin support tools so I must use
Linux how Host.
I can have the RedHat 7.3 Linux version already installed in headquarters
of my factory.
Before to require and install that, is it a valid host environment for
rtems tool-chain ?
What is the best (another version, another type eg:SUSE, MANDRAKE) ?

Thank you
