Subject:	patch for fsext.h
Mime-Version:	1.0

--=====================_881006199==_
Content-Type: text/plain; charset="us-ascii"

Like the patches I posted late last week, this patch:
	* is relative to the last alpha (971114)
	* associates a state pointer with the file descriptor for the fsext
	* adds some new low-level io emulation

The difference from last week:
	1. adds __FSEXT_fstat for future (soon) emulation
	2. I forgot to have __FSEXT_alloc_fd associate the state variable as well. 

(The changes are very small relative to last weeks)
the patch for fsext.c will follow shortly
