You could copy the DJGPP libc source code for exit() into you own code
and customise it by adding a printf().  Then any call to exit() would
run your own version (Not sure about the licence issues though).

At the command line you can use the redir utility with the -x switch:

C:\>redir -x myprog
MyProg ...
... done.
Exit code: 123
