Out of interest I did a ``make all'' on the 3.1-R GENERIC kernel and
these are my figures. My machine is an AMD K6/233 (an original K6,
not a -2), 64MB memory, 128MB swap, U/W SCSI HD:
normal
Make all 4:25
Kernel size 2.2 MB
Directory size 6.3 MB
Are the clock and clock multiplier jumpers set correctly on your
m/b ;-).
