Yes, the segv is gone.  But it still doesn't work properly :-)

I've attached some files as an example of the failure.

	x86_64-unknown-netbsd-gcc -traditional-cpp -M \
	    -D_LOCORE -Dx86_64 -D_KERNEL microtime.S

In file included from microtime.S:36:
asm.h:71: unterminated #ifdef
asm.h:64: unterminated #ifndef
asm.h:41: unterminated #ifndef

Also attached is the output of:

	x86_64-unknown-netbsd-gcc -traditional-cpp -E \
	    -D_LOCORE -Dx86_64 -D_KERNEL microtime.S

Look for "SHOULD NOT BE HERE" and "NEITHER SHOULD THIS".  Also note that
the _ENTRY() macro (used by ENTRY()) from asm.h does not get expanded.
