     3 I tried to use crosstool-ng to generate a toolchain for Linux on big

     4 endian arm with recent versions of gcc, glibc, etc... but had a few

     5 problems.

     6 

     7 It appears that the gcc patch (for gcc 4.2.x)

     8 for big-endian arm (240-arm-bigendian.patch) lacks the change attached

     9 to this mail as 240-arm-bigendian2.patch.
