Subject: uncompress and estdio

Attached below is a patch to estdio that was posted to comp.os.minix
awhile back. Last time I looked, the linux version of estdio did *NOT*
have these patches applied. Maybe that's what causes the uncompress
problem?

I noticed another bug in estdio/fread.c. It does not set the _IOEOF flag
when hitting EOF during an __ioread() call.

The diff below fixes it and included the previously known bug with
readsize. I don't know if this fix catches all situations, it works for
me.

      if (reed != 0) {
        if ((readsize -= reed) >= leftover) {
