The problem here is that the startup code (c.o or whatever) refers to the 
routine __main in the libraries, which in turn refers to your main routine.
Since you are linking with the registerized library, it calls main as a
The at sign before the name indicates the routine is being called registerized;
the underbar indicates it is being called stack-based.  This prevents a
possibly catastrophic mix of registerized and stack-based calls, and instead
results in a link error (like this one).

The fix is one of two things:

1. BEST - stick in a prototype for main.  This will cause __main to call it
   registerized and everything will work fine.

2. NOT SO GOOD - link with lc.lib BEFORE lcr.lib.  This will resolve the
   symbol __main to the NON-registerized version.  It will also resolve any
   other library routines that you didn't include the prototype for, which
   hopefully is none of them.  This method has the disadvantage of hiding
   non-registerized calls that you may not have intended to be 
   non-registerized.
