Need advice on converting programs from Borland C compiler

[David J. Stelte]

I have a few programs that were written for DOS and compiled under the 
Borland Turbo C compiler that I need to convert to run under the Linux 
like environment in Cygwin.  The code has a lot of cursor positioning 
function calls like gotoxy(), makes use of screen colors using a 
function called cprintf(), and has some functions for getting getting 
special characters from the keyboard like F1-F12.  Is there a library 
that comes with the native GCC that comes with Cygwin that has these or 
similar functions?  I can't seem to find it.  Advice...?
