DOS limits the number of file descriptors (i.e., handles which are
returned by open() function) to the minimum of two numbers: the
value of your FILES= setting and 255.  DJGPP 1.x supports upto 45
handles, but the number of files you can fopen() is further
limited by the size of the table which holds all the FILE objects.
This size is currently 20, unless you recompile the library.
