Undefined Reference??

[Mark Koi <koi at ssa dot crane dot navy dot mil>]

I have installed both gnu-win32 and mingw32 but both
packages give me the same error.  It must be an option
or something.  My brain is fried.

gcc -o myprg.exe myprg.c

Error:
c:\windows\temp\cc9350811.o   : undefined reference to 'SetTimer@16'
GCC.EXE: Internal compiler error: program ld got fatal signal 1

program:
-------------------------------------------------------

#include <stdio.h>
#include <windows.h>

VOID
CALLBACK handler(HWND hwnd, UINT umsg, UINT id, DWORD dwTime)
{
   fprintf(stdout,"Callback invoked dwTime=%d\n",dwTime);
}

int
main(int argc, char **argv)
{
    UINT cc;

    cc=SetTimer(NULL, 0, 500, (TIMERPROC) handler);
    if (cc == 0) {
       fprintf(stderr,"SetTimer failed\n");
       exit(-1);
    }
    fprintf(stdout,"Created timer succesfull\n");
    Sleep(10000);
    fprintf(stdout,"After sleep \n");
}
