1. Purify errors fixed. Only known leaks are within the toolkit,
   the Athena text widget, and XPM.

2. Code was ansi-fied. You will need an ANSI compiler (such as gcc)
   in order to compile the code. Sun's acc and V3 cc work too.

3. Xmail is ported to Linux (works with yggdrasil and slackware versions).
   See note below about the preserve button.

4. All known coredumps have been fixed.

5. Works with X11R6, however xmail isn't fully I18N compliant. Also,
   if you're compiling on a Sun, please remove the -Xc flag from
   the CCOPTIONS before compiling callbacks.c .  -Xc undefines the
   sigaction structure, which is required by callbacks. Other than that,
   it works fine. 

6. General portability problems cleaned up, although I suspect there
   are more (DEC Alpha would be an acid-test).
