> Warn :  (1,1):No module definition file specified: using defaults

This is a warning, not an error and it is correct.  All 16 bit Windows
programs use a module definition (*.DEF) file to specify stack size, heap
size, segments and things like that.  You did not have one in your project
so the linker used the default one, DEFAULT.DEF, and told you what it had
done.  If you don't like the warning then supply a module definition file.

> Error:  (1,1):Undefined symbol _cprintf in module color2.c

Open color2.c in the IDE editor.  Place the cursor on the word cprintf.
Press Control-F1.  The help for that function will appear.  Click on
Portability.  You will see that it is not available in a 16 bit Windows
program.

Repeat for textbackground and textcolor and the results are the same.  They
are not available in a 16 bit Windows program.  Adding function prototypes
for them does not supply the functions.  It just allows the compiler to
proceed as if such functions would be available, pushing the errors out
until later.  When the linker tries to bundle all needed functions into an
executable you get an unresolved external error.

Go to the project window.  Right click on the exe name.  Select TargetExpert
from the menu which appears.  Set the platform for DOS and click Ok.  Then
do a Project|Build_All.
