make ungetbuf an unsigned char (forgot to cast back to unsigned in
fgetc_unlocked).  This was the bug that broke bzip2!  Hooray!

MYARCH=$(shell uname -m | sed 's/i[4-9]86/i386/')

# This extra-ugly cruft is here so make will not run uname and sed each

# nothing has to be done from 1 sec to 0.12 sec on a 900 MHz Athlon.
