You can easily write it yourself, using the library function 
__dosexec_find_on_path.  For example (untested!):

  #include <stdio.h>
  #include <stdlib.h>
  #include <libc/dosexec.h>

  int main (int argc, char *argv[])
  {
     char full_path[FILENAME_MAX];
     extern char **environ;

     if (argc <= 1)
       {
	 printf ("Usage: %s progname\n", argv[0]);
	 return 0;
       }

     if (__dosexec_find_on_path (argv[1], (char **)0, full_path) == NULL &&
	 __dosexec_find_on_path (argv[1], environ, full_path) == NULL)
       printf ("%s: Command not found\n", argv[1]);
     else
       printf ("%s\n", full_path);

     return 0;
  }
