libgmp: duplicate symbol

[Christoph Egger <Christoph_Egger%gmx.de@localhost>]

Hi,

when building tools for NetBSD/amd64 on Mac OSX 10.5 configure for mpfr
fails with:

[...]
checking dynamic linker characteristics... darwin9.8.0 dyld
checking how to hardcode library paths into programs... immediate
checking whether stripping libraries is possible... yes
checking if libtool supports shared libraries... yes
checking whether to build shared libraries... no
checking whether to build static libraries... yes
checking whether gcc __attribute__ ((mode (XX))) works... yes
checking for recent GMP... yes
checking for __gmpz_init in -lgmp... no
configure: error: libgmp not found or uses a different ABI.
Please read the INSTALL file -- see "In case of problem".
*** [.configure_done] Error code 1


Looking into the config.log I find this error:


ld: duplicate symbol ___gmpz_abs in
build/tooldir.amd64/lib/libgmp.a(memory.o) and
build/tooldir.amd64/lib/libgmp.a(lt22-init.o)


Attached is a fix. Please review.

Christoph
