The RPMs are built on an old Pentium Pro running Redhat 5.2 for
for glibc compatibility reasons.  It has a pretty fast disk subsystem
and the builds are not THAT bad.  

OAR's Solaris machine is an SS5.. It took 43 hours to build JUST the
gcc/newlib tools on it.

RPMs normally associate a -REVISION on the RPM to indicate patch
level.  So you end up with something like this:

sh-rtems-gdb-4.18-4.i386.rpm

indicating that this is the fourth round of RPMS for sh-rtems
on gdb 4.18.  For gdb 5.0, we would reset to revision 1.

I am sorry to hear that.  I have four kids.  When they are sick it 
really disrupts the normal routine of life.

This seems too small... what is in them?  I have a size report for
i386-rtems RPMs here:

Out of curiousity, is this a good way to present the installed
sizes?

I am curious how it goes.  I think I worked the issues out building on
the 3 OSes I did.
