Hi All,

I am writing a little demo in C++ to get back up to speed with
graphics programming, and explore the many features of
DJGPP and in doing so come across these messages when my demo is
built by the make file (at the bottom of this message):

Could someone please explain what 'linker input file unused since linking
 not done' means.

Are these messages important or can I just ignore them?  The executable
that is built seems to work fine?

Thanks in advance

John
