Can C-Free programme for Windows DLL?
Yes. Please see "Project templates" of C-Free Help.

Can I use other function libraries in C-Free?
Yes, you can use other function libraries in C-Free. Before building your program, you must add the function libraries' paths into C-Free's building Directories. For example you must add the "Include Files" path. Please reference to the "Directories" of C-Free Help.

When I include conio.h in my program, I always get linking errors.
It is an irregularity. When you use conio.h in your program, you will get linking errors such as:
undefined reference to 'clrscr'
you have two methods to remove the errors:
(1) Include "conio.c" in your program. you may write code as "#include <conio.c>" in your program.
(2) If you work your program with a project, you may add the file "conio.c" into your project. (The file "conio.c" is located at C-FreeInstallDir\mingw32\include ) 

How can I upgrade the compiler used in C-Free?
C-Free supports multiply compilers. Please refer to the following links for compiler supports:
MimGW    Cygwin   
Borland C++    Digital_Mars_C/C++   
Open_Watcom_C/C++
