Further discussion with Aharon Robbins and Mike Brennan brought forth this information:
a) X/Open awk uses standard printf formatting, which does not produce
leading 0's.
b) platforms which produce leading 0's (Solaris, AIX, HPUX, IRIX64)
do this as a legacy (pre-standardization) feature.
c) if mawk was built on such a platform, it would have produced leading
0's, built on other platforms it did not.
d) Aharon Robbins changed gawk to no longer produce leading 0's.
So I modified mawk to explicitly not produce leading 0's, for consistent
and conformance with the standard. That change is in the 20090820 snapshot
