It has nothing to do with clean code. The problems are PURELY bugs in
gcc, which the gcc developers refuse to test before releasing (they
could at least try compiling a few apps that use inline asm before
making a release, such as MPlayer or ffmpeg), and which they sometimes
even refuse to fix (see the infamous quote in Michael's old sig).

If you insist on using buggy compilers, you're on your own. Don't
complain to us. I would recommend using 2.95.3, which has never been
known to give ICE or spilled register errors.

P.S. Many of the bugs in gcc don't only happen with inline asm. I know
I've seen spilled register before in other cases and it's purely a gcc
bug.
