I tried to use crosstool-ng to generate a toolchain for Linux on big |
| yann@1128 | 4 |
endian arm with recent versions of gcc, glibc, etc... but had a few |
| yann@1128 | 5 |
problems. |

It appears that the gcc patch (for gcc 4.2.x) |
| yann@1128 | 8 |
for big-endian arm (240-arm-bigendian.patch) lacks the change attached |
| yann@1128 | 9 |
to this mail as 240-arm-bigendian2.patch. |
