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: - compiler-gcc+.h: add the missing noinline and __compiler_offsetof - compiler-gcc4.h: new file based on the corrected compiler-gcc+.h - compiler.h: include compiler-gcc4.h 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.
