This is likely to require very non-trivial changes to gcc or clang. The major issue is that the process needs to be in a known initial state before beginning a compile - and it's very unlikely that the compiler cleans itself up enough to return to that state. If you really want to trim low-hanging fruit, try disposing of libtool and GNU configure instead - their overheads are _many_ orders of magnitude higher than make exec()ing gcc. -- Peter Jeremy
