Let's make sure we're talking about the same problem.

There's at least two problems with process.c -- one causes egcs
to crash building process.c, the other causes gcc-2.8 to mis-compile
process.c.

[ They may actually be the same bogus asm statement -- I don't know. ]

I know that newer 2.1.x kernels have the fix for the gcc-2.8 mis-
compilation.  I don't know if those kernels have a fix for the
egcs abort when compiling process.c.

[ Note the next egcs snapshot will have the ADDRESSOF optimizations
  so the mis-comilation problem will be an issue for egcs real soon.]
