I'm working with a 2.97 based compiler for x86-64. There are a few
miscompilations, but they're probably more attributable to the immature state
of the x86-64 port than the generic compiler. The first thing
that is noticeable are lots of warnings now spewed out by the compiler.
Appended patch fixes the __setup related at least.
Other common ones are token after #endif (mostly #ifdef X .. #endif X)
and semicolon/label at the end of switch.
