There is an
	extern int near _nfiles;

which you can set to the new value specified through DosSetMaxFH.

Another solution is to modify to startup file CRT0DAT.ASM, uncommenting
a few lines which are there just to do the DosSetMaxFH and set _nfiles.
It uses a defile called NFILE, which you may have to modify in stdio.h.
