Hello Jun,
The file is the common time.c from linux/arch/mips/kernel as you
can see from the third to last line of Hanshi's email. The tools
he is using are from H. J. Lu's RedHat 7.1 RPMs on the oss.sgi.com
ftp site. The file compiles just fine with the little endian version
of the same tools from the same place.
Hanshi and I will look at the USECS_PER_JIFFY_FRAC macro. Thanks for
the pointer.
