This layout is actually quite convenient, just change your path and you
have a different version:

The trick is basically to run fpc with two switches, and a modified $PATH:
    - [-n]:   One that disables the default config file
    - [@XXX]: One that specifies where to look for the config file. (as
the quoted text states this should not be required, yet somehow it was for
my setup -- I'll need to look into this)

So than you have something like (for revision 26651, obviously):
===== fpc-26651 =====
#!/bin/sh
PATH="/compilers/fpc/26651/bin":$PATH" fpc -n
@/compilers/fpc/26651/etc/fpc.cfg "$@"
===== ========= =====

I'm not sure if that is really what you need, but I think this is the most
flexible/straightforward method of `running one fpc.cfg per fpc version`.
