The current way is broken. Some qemu header files are a complete mess. qemu-common.h and sysemu.h are good examples. They include too many things, if you change them a lot of code will be recompiled. I could make the problem less worse by moving all compiler related macros to a compiler.h header and then include it in qemu-common.h and error.h. This way error.h won't be affected, although the real problem will remain unsolved.
