ld crashes with segmentation fault when linking with libmpir.a

[Daniel R. Grayson]

ld crashes with segmentation fault when linking with libmpir.a

To reproduce:

    wget http://mpir.org/mpir-2.6.0.tar.bz2
    tar xjf mpir-2.6.0.tar.bz2
    cd mpir-2.6.0
    ./configure --build=x86_64-pc-cygwin
    make
    ld -u __gmpn_gcdext .libs/libmpir.a

Since gdb doesn't show me any useful information (the stack is
destroyed), it's hard
to tell whether this is a cygwin problem or an ld problem.  It doesn't
happen under
Mac OS X or under several flavors of linux.  If you think it's an ld
problem, let me know, and I'll report it to the binutils people.

Output from cygcheck -s -v -r is attached.
