I have, occasionally.  Consider a directory (bigapp.d) containing a
large applications (bigapp), where you want you have some smaller
associated utilities (ut1, ut2, ...) which use routines in bigapp.  It
does not always make sense to group the routines shared by the large
application with one or more of the utilities into a library in a
separate directory.

Now bigapp.c, ut1.c, ut2.c, etc., each must have a main().  This is
annoying for use with debuggers, cross-referencers, etc.  In the above
situation it makes a lot of sense to have each routine in bigapp.d
named differently.  It would be nice for the entry point for the ut1,
ut2, ... executables to be named ut1(), ut2(), etc.  The entry point
in bigapp.c could be called main() or bigapp() depending on taste.
