I tried redir for some DJGPP 1.x programs and got trouble. So I took
Borland C and compiled:

/****************************************************************/
/* usage: stderr  stderr_file_name file_to_execute arguments ... */
#include <stdio.h>
#include <process.h>

int main(int argc,char**argv)
{
	int ret;

    /* redirect standard output to a file */
    if (freopen(argv[1], "w", stderr)== NULL)
       return fprintf(stderr, "error redirecting stdout\n");

    ret=spawnvp(P_WAIT,argv[2],argv+2);
    fclose(stdout);
    fclose(stderr);
    return ret;
}
/****************************************************************/
