The "problem" is that gawk now pays attention to locales.  If you
set LC_ALL=C in your environment, you get the same behavior as the
old version.  Alternately, you can fix your program so that locales
won't affect it:

--- maketypes.awk       2003-02-06 15:31:48.000000000 +0200
+++ maketypes2.awk      2003-02-06 16:37:32.000000000 +0200

Hope this helps,
