[1.] One line summary of the problem:    
make oldconfig can change Alpha system type on 2.2.19

[2.] Full description of the problem/report:
With the system type set to `Cabriolet' (CONFIG_ALPHA_CABRIOLET)
running make oldconfig causes it to change to `EB64+' (CONFIG_ALPHA_EB64P)
without asking.

(See end for probable cause.)

[3.] Keywords (i.e., modules, networking, kernel):
kernel, configuration, alpha

[4.] Kernel version (from /proc/version):
Linux version 2.2.19 (bacam@kamelion) (gcc version 2.95.2 20000220

     problem (if possible)

       (please look in /proc and include all information that you
        think to be relevant):

[X.] Other notes, patches, fixes, workarounds:

The Configure script chooses the old value for a `choice' by testing
each possibility in turn and using the last one.  Now choosing
Carbriolet also sets EB64P, but EB64P is later in the choice list and
thus is chosen as the default (and the Cabriolet setting is ignored).
