Problems install gmp 5.0.5 on Powermac Quad with OS X 10.5.8

[Christian Calderon]

The install failed during the make phase of the build. I configured as  
so:

./configure --prefix=/opt/gmp/5.0.5 --enable-cxx --enable-assert -- 
build=powerpc970-apple-darwin9.8.0

The configure succeeded, so the next thing I did was:

make

During the make process lots of warnings came up about  
'__gnu_inline__' being ignored.

The last four lines were

ld: duplicate symbol ___gmpz_abs in .libs/compat.o and .libs/assert.o
collect2: ld returned 1 exit status
make[2]: *** [libgmp.la] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

Is this because of the --enable-assert option? I just included that  
because the .info file said it was helpful for debugging in the  
installation section. Or is it something else?
