The attached patch fixes a SEGV described in:

        http://sources.redhat.com/ml/gdb-patches/2004-07/msg00290.html

I followed Daniel's recommendation and made this change for all N32/N64
mips targets.

2004-07-22  Joel Brobecker  <brobecker@gnat.com>

        * mips-tdep.c (mips_gdbarch_init): Set size of long double
        to 128 bits for N32 and N64 ABIs.

Tested on mips-irix.

OK to commit?
