Can TCC be modified to compile with Emscripten? If not, where can I find an x86-generating C compiler that does?

IOCCC 1986/wall.c - why does TCC beat GCC in handling earlier C code?

Another pearl from the early IOCCC years is Larry Wall's 1986 entry: http://www.ioccc.org/years.html#1986 (wall) I suspect there is no C compiler today that can actually compile that source straight-out-of-the-box, due to the severe preprocessor…
