Sorry for this very late reply. Finally back in Windows, before building
the latest pretest (21.2.93), I thought of compiling those two previous
versions as you suggeted, comparing, stripping, etc. But, I ran into two
obstacles:
  1 - 21.2.90 failed to compile with MinGW 2.0 (gcc 3.2)[1], and
  2 - in the shuffle of source and binary tarballs from three different
      pretests, I accidently rm'ed the gcc 2.95.2-compiled binaries of
      21.2.90.

The current pretest built and installed w/o problems on
w98se/P3-667Mhz/128Mb w/ MinGW gcc 3.2/make 3.79.1
(and, for what it's worth, resulting binary sizes are nearly identical
to those of 21.2.92).


[1] It may be irrelevant now, but compilation of 21.2.90 failed w/ gcc
3.2, with the following output:

All the best,
