c++.dos - HOWTO: compiling for DOS

Hello,
my envirnment is XP, but I need to compile for DOS.
When I try to compile the TSRCLOCK.c sample from dm-site then I get the errors
below.
The DOS libs and tools are copied to the correct directories;
it looks like the target (DOS) is not well specified.
I also tried -msdw but that too brings the same error.
What is the correct dmc compile option for DOS (tiny or small mem model)?
dmc -mti TSRCLOCK.c
intdos( s, s);
^
TSRCLOCK.c(85) : Lexical error: unrecognized token
int86(0x10, s, s);
^
TSRCLOCK.c(107) : Lexical error: unrecognized token
int86(0x10, s, s);
^
TSRCLOCK.c(110) : Lexical error: unrecognized token
int86(0x10, s, s);

TSRCLOCK.c(117) : Lexical error: unrecognized token

Hello,
I haven't had a look on the dm-site and the example DOS-code.
I assume there is some header file missing.
Here is a example that I can compile:
//--------- e.cpp -----------------
#include <dos.h>
int main(int argc, char*argv[])
{ union REGS rin, rout;
intdos( &rin, &rout);
int86(0x10, &rin, &rout);
return 0;
}//main
//---------------------------------
Compile and compiler output:
D:\TEMP>dmc -mti e.cpp
link ct+e,e/noi;

Don't execute the resulting program as the register union rin
is not initialized!
