Subject:  rewind-bug fixed
Precedence: bulk

Hello, workers,

The problem with rewind and files opened "r+" turned out to be
very simple. Applying the following patch seems to fix things:

--- src/libc/ansi/stdio/rewind.old	Mon Dec 26 15:34:52 1994
+++ src/libc/ansi/stdio/rewind.c	Sat Jun 20 14:40:16 1998
@@ -8,6 +8,7 @@ void rewind(FILE *f)
 {
   fflush(f);
   lseek(fileno(f), 0L, SEEK_SET);
+  f->_fillsize = 512;	/* See comment in filbuf.c */
   f->_cnt = 0;
   f->_ptr = f->_base;
   f->_flag &= ~(_IOERR|_IOEOF);

Hope this helps.
