Subject: problem with here documents in tcsh on cygwin v1.0 cdrom

Here is a bug report with a fix for tcsh from /contrib on the
Cygwin v1.0 CDROM.  I hope that this is the right place to
post this to get this to whoever maintains tcsh for cygwin.

Tcsh writes the contents of the here document into a temporary file.
When tcsh processes a second here document, it does not discard the contents
of the first here document.  Here is an example of the bug

"F:/ro/bin/bash.exe"-2.03$ /contrib/bin/tcsh
> cat <<END
? long long long
? END
long long long
> cat <<END
? short
? END
short
ong long


Here is the change I made to fix it:

diff -c tcsh-6.09.00/sh.dol.c tcsh-6.09.00.works/sh.dol.c
*** tcsh-6.09.00/sh.dol.c	Sun Oct 25 07:10:04 1998
--- tcsh-6.09.00.works/sh.dol.c	Sun Jan 30 10:20:50 2000

*** 1009,1015 ****
  #ifndef O_TEMPORARY
  # define O_TEMPORARY 0
  #endif
!     if (open(tmp, O_RDWR|O_CREAT|O_TEMPORARY) < 0) {
  	int     oerrno = errno;
  
  	(void) unlink(tmp);
--- 1009,1015 ----
  #ifndef O_TEMPORARY
  # define O_TEMPORARY 0
  #endif
!     if (open(tmp, O_RDWR|O_TRUNC|O_CREAT|O_TEMPORARY) < 0) {
  	int     oerrno = errno;
  
  	(void) unlink(tmp);



In order to compile tcsh I had to make an addtional small change:

	take the source code to tcsh from the contrib sources
on the Cygwin v1.0 CDROM

	apply the patch tcsh-6.09.00.p0, from the contrib patches
		the last hunk will be rejected,
		and if you try make it will bomb out with :
			tc.os.h:534: conflicting types for `gethostname'
		but then apply the following patch and it will compile:

diff -c tcsh-6.09.00/tc.os.h tcsh-6.09.00.works/tc.os.h
*** tcsh-6.09.00/tc.os.h	Sun Jan 30 16:33:36 2000
--- tcsh-6.09.00.works/tc.os.h	Sun Jan 30 09:31:56 2000
