All that I can think off is that you have attempted to call a function
that the
linker ('cause this error is generated by ld, the DJGPP linker) is not
able to find.
Check what files you feed gcc on the command line: somewhere you are
short an object (.o) file that contains this function.

Another fing: you need to define this func as an "extern" prototype in
the file you use it in (or in a generic .h "header" file).

The summary is this: this error is generated by the linker, so look at
the files you
are linking when this happens. One of them seems to be short this
function.

Hope this helped!
