I'm not sure about this, but you may want to comment out the #include
<conio.h> that has the "old" definition.  If this causes other problems,
then you can probably safely ignore the warning.

The -l option must go at the END of the command line because ld is a
one-pass linker.  When it finds a library on its command line, it
resolves any and all unresolved externals on the spot, and then discards
the rest.  For example:

  gcc -o prog.exe -lcurso main.o part1.o part2.o

This will not work because at the time the linker sees '-lcurso', there
are no unresolved externals.  Changing the above to:

  gcc -o prog.exe main.o part1.o part2.o -lcurso

will work.
