Subject:	Creating a library

        I still can't get the library to link. I create the library, put it 
in c:\djgpp\lib, as libwatcp.a, then use gcc -o merc -lwatcp.a *.o
        It compiles fine, but when it tries to link I get lots of undefined 
refernces. It is finding the library, but not the symbols. If I run nm -s 
libwatcp.a, it has the functions as _<FunctionName>. So the functions are 
there, but not being found.....Very frustrating...
        Here are the makefiles for the library and my routines....

                Any help would be appreciated.

                        Martin.
