Build error in gmp 4.2.2

[Michael J. Bauer]

The pertinent info section was not an absolute order; it was merely 
indicating the environment.  I should have put the setenv before the 
configure; that's how I ran the initial build.

The difference between what I did and the officially approved method of 
setting ABI should make no operative difference in result from my prior 
attempt; both my earlier setenv and the command-line assignment set the 
environment variable ABI to 64 for configure and make.  The only 
difference is that my earlier method set ABI as a global environment 
variable in tcsh; this way I feed it individually to each of the two 
build commands (configure and make).

Note that the same error also happens with no ABI selected (which 
implies 64) and C++ support turned on.  However, there is no problem if 
I leave C++ support disabled, no matter what method I use to set the ABI 
on configuration.

Having just rebuilt with what appears to be the officially approved 
means of setting ABI:

# ./configure --prefix=/usr/local/package2 
--oldincludedir=/usr/local/package2/include --enable-cxx ABI=64
(This time around, ABI is not set as a global environment variable in 
tcsh; it's just fed to configure and later to make.  )

As expected, I still get the identical error on make:

# make ABI=64

For comparison, here's an earlier stretch in the non-C++ section:

The state of the build tree after the errors is instructive:

# pwd
/tmp/Software/gmp-4.2.2
# file memory.o
memory.o:       ELF 64-bit MSB relocatable SPARCV9 Version 1, 
UltraSPARC1 Extensions Required
(This is a representative; every .o file in this directory, save one, is 
ELF 64.)
# file dummy.o
dummy.o:        ELF 32-bit MSB relocatable SPARC Version 1
(This is the one.)
# cd cxx
# file osfuns.o

(This is a representative; all of the .o files in this directory are ELF
