The last step isn't required at all (DJGPP does it for you).  However,
the space allocated to the FILE objects is currently limited to 20 in
DJGPP (look in the library source, file libsrc/c/io.findiop.c).  So
functions which return FILE * are limited to 20, unless you recompile
the library.  Functions which return file handles don't have that
restriction.
