I would hope that RPM would tell you so. :)

I would like to thank Ralf also.  It really has made a lot of
difference.
I have hacked a bit here and added gnat RPMs but they are mostly Ralf's
baby.
Ralf also contributed the Linux->Cygwin cross RPM specs in contrib
if anyone besides Ralf and I has ever noticed.  I now use those to
build Cygwin hosted tools while comfortable on my fast Linux box. 
I have also used those as baselines to do the same thing for Solaris
but I don't have all the kinks worked out. 

The big things about RPM from my perspective is that everyone is
using the same binary I am so there are fewer problems from tools.
And it certainly makes it easier to switch tool set versions in 
and out.  Much easier to support over all.

I have to concur with you.  I move the development environment 
around a lot more than I used to.  I just upgraded to a 2.2 Ghz machine
from the old dual P2 333 I had used and things just scream.  I now
build about 130 configurations before each snapshot.  Sad to say 
problems till creep through though.
