Here's a small program that I wrote that seems along these
lines.  It's really just a useful emulation of the Un*x which
command -- compile to which.exe and place on your path :)

/* You are free to use and do whatever you want with this code */

#include <stdio.h>
#include <dir.h>

int
main(int argc, char **argv)
{
  int i,j;
  const char *ext[] = { "com", "exe", "bat" };
  const char* where;
  char buf[256];    /* if this is not big enough, get a life */
  for (i=1; i<argc; i++) {
    where = NULL;
    for (j=0; j<3; j++) {
      sprintf(buf, "%s.%s", argv[i], ext[j]);
      if ((where = searchpath(buf))) {
	printf("%s\n", where);
	break;
      }
    }
    if (where==NULL)
	printf("%s not found\n", argv[i]);
  }
  return 0;
}
