Hi,
It looks like the libtool script is dropping the -m64 during link.
Recall that path-prefix-10.6's g++ (compiler_wrapper) is set to i386
(32b). This is why libgmpxx.4.dylib-master.o is built for i386, which
causes subsequent links to libgmpxx.dylib (x86_64) to fail.
Peter (our libtool-er), can you comment on my observation? Is
this a possible libtool bug? gmp-5.0.1's ltmain.sh is from libtool
2.2.6b.
Relevant log exceprt below (note the link command):
