Development host preferences?

[antispam21 at verizon.net (mike)]

Hi all,
Please forgive me if this is a dumb question:

We are using an i386 Linux box running Redhat 2.4 for RTEMS development.
It has been working fine to cross compile for a sparc target (gcc,
grmon, gdb etc..) .
However, the version is pretty old. The questions are:

- is it a good idea to switch to Fedora?
- Any prefer Fedora version?
- Any potential problem if we switch?

Thanks for any comments and inputs. They will be greatly appreciated.
