This is not a big deal but here's the Changelog from 2.5.2 -> 2.5.3:

Changes between release 2.5.3 (29May96) and release 2.5.2:

        - Some serious bugs in yymore() have been fixed.  In particular,
          when using AT&T-lex-compatibility or %array, you can intermix
          calls to input(), unput(), and yymore().  (This still doesn't
          work for %pointer, and isn't likely to in the future.)

        - A bug in handling NUL's in the input stream of scanners using
          REJECT has been fixed.

        - The default main() in libfl.a now repeatedly calls yylex() until
          it returns 0, rather than just calling it once.

        - Minor tweak for Windows NT Makefile, MISC/NT/Makefile.

I can send a set of diffs but it's probably just easier to
grab the distribution from ftp.ee.lbl.gov.
