Would something like this work?

Call __dosexec_find_on_path with a local copy of the
environment variable PATH;

if non NULL, retrieve and display the result from *buf;

replace the local copy of the path string with the substring
starting at the end of the path for the command just found;

call __dosexec_find_on_path again with the substring;

continue subsetting your local path string until
__dosexec... returns NULL.
