make bootstrap fails, "parse error" at objc.h:51, internal error

[Sandro Hawke]

Using RedHat 6.0 on a generic Pentium II/400-EIDE system.  egcs from cvs
today (May 7, egcs-2.93.21) and identically with -D 4/8/99.  No
options to configure.  34 minutes into "make bootstrap", the make ends
with:

I am able to complete the build by excluding Objective C from the
enabled languages, so this is just FYI.  (I don't have a clue how to
debug this furthur.)  I orginally bootstrapped from the default RH
gcc, which was egcs-2.91.66.  I did build egcs-2.93.21 (without ObjC)
the other day, so that's my starting point now.
