>/usr/include/machine/cpufunc.h: In function `getreg':
>/usr/include/machine/cpufunc.h:203: impossible register constraint in `asm'
This seems to be a compiler bug. The compile works with the default CFLAGS
of -O2. The asms in cpufunc.h work in the kernel with -O. They never work
with -O0.
Why does `make' delete the C source file created by yacc? `make depend'
cannot work right without this source file.
