compile C program to MS-DOS environment

Question

i have a small program that uses 32bit object file, and i wish to run it under dos operating system. now, after searching i found DJGPP.
is there a way to use DJGPP to compile my program to 16Bit dos executable format?

thanks in advance

You want to run 32-bit protected mode code from that object file on a 16-bit real mode operating system? — Hans Passant, Apr 22 '10 at 15:04

If you want to take advantage of a 32-bit processor (386 and above) to run 32-bit code under 16-bit DOS (using DPMI), then DJGPP is definitely the right tool. That is, it produces 16-bit dos executable files containing 32-bit code. For object format it uses 32-bit COFF.
