I ended up subscribing to the rpm mailing list, and got some excellent 
advice from a guy by the name of Jeff Johnson, who is apparently one of 
the lead rpm developers at Redhat.

Seems that the ctype stuff that was blowing up for me when trying to 
build rpm-4.0.3 was actually a problem with bzip2.  Once I rebuilt bzip2 
against the new glibc-2.3.2, i had no more problems building rpm-4.0.3.

But I still really needed rpm-3.0.6.  When trying to build it, it kept 
blowing up with "popt.c:596: `FLT_MAX' undeclared" errors.  Seems that 
this is just a small if/else test for min/max values of a float, and 
commenting out the test lets the rest of the build process complete 
successfully.

So i'm now back in business with a new rpm-3.0.6.

Thanks to all that gave me suggestions.
