Hello,

While building a toolchain with crosstool-NG 0.19.0, I ran into a
conflict between GMP 5.1.1 and PPL 0.11.2:

   .build/src/ppl-0.11.2/src/mp_std_bits.defs.hh:48:7: error:
redefinition of 'class std::numeric_limits<__gmp_expr<__mpz_struct [1],
__mpz_struct [1]> >'

I backported the attached patch from the PPL mailing list [1] to PPL
0.11.2 and successfully used it in crosstool-ng as 
ct-ng.1.19.0/patches/ppl/0.11.2/400-fix-redefinition-numeric-limits.patch.

Please let me know if this is not the proper way to suggest a patch to
crosstool-ng.

Thanks,
Malte
