Author: aldot
Date: 2007-01-22 11:17:23 -0800 (Mon, 22 Jan 2007)
New Revision: 17473

Log:
- don't rely on buggy gmp/mpfr on the host but use our own build iff we are about to build a somewhat current toolchain.


Added:
   trunk/buildroot/toolchain/gcc/4.2/900-gengtype-verbose-error.patch

Modified:
   trunk/buildroot/package/gmp/gmp.mk
   trunk/buildroot/package/mpfr/mpfr.mk
   trunk/buildroot/toolchain/binutils/binutils.mk
   trunk/buildroot/toolchain/gcc/Config.in
