From: Adrian Bunk <bunk@stusta.de>
With the release of gcc 4.0 being only a few months away and people
already tring compiling with it, it's time for adding a compiler-gcc4.h .
This patch contains the following changes:
- remove compiler-gcc+.h
- compiler-gcc4.h: new file based on a corrected compiler-gcc+.h
- compiler.h: include compiler-gcc4.h for gcc 4
- compiler.h: #error for gcc > 4
- compiler-gcc3.h: remove __compiler_offsetof (there will never be a
gcc 3.5)
small indention corrections
I've tested the compilation with both gcc 3.4.4 and a recent gcc 4.0
snapshot from Debian experimental.
