- gcc 2 does no insn scheduling for the 386 / 486. With -m486, it chooses
- slightly different instruction sequences, and aggressively aligns loops

- The PIC scheme it uses is intended for SysVr4, which I am told is
- similar to the SunOS scheme.

- Compiling machdep.o with gcc2 causes the kernel to crash during
- bootstrapping for some reason. I hope to look into it this weekend.
