Hi all,

With the growing number of people starting to help out with getting DJGPP
fully working on Windows 2000 and other people wanting to know where it is
at I have decided to start sending out my status report on where the DJGPP
compiler & packages is up to with regards to Windows 2000 once a week. I
have for my own sanity had to produce the status report so that I know where
I have been, where I am up to and where I am going.

There has ben allot of progress as you have seen in this list over the last
6 weeks by others and myself with regards to geting DJGPP fully working on
Windows 2000.

This week the major milestone acheived in my opinion was that I can now use
the latest version of Rhide to compile test/debug sample code for fixing Win
2000 issues that I have found. There are still issues and crashes occuring,
but it can be done. This is with LFN enabled.

I will be sending the attached status report out every Sunday until it is no
longer required (or I am on holidays).  The report is an attachement as
allot of the lines are very wide and workwrap would make it unreadable on
standard email packages.

Hope this helps.

Regards
Andrew

DJGPP & WIN2K OUTSTANDING ISSUE / TESTING REQURIED

1) LFN issues
2) IOCTL issues
3) redirection
    a) Btw, I cannot find it in my records, but I'm pretty much sure =
someone
    reported that redirection of stderr doesn't work on W2K as well.  So
    trying "redir -e foo", and the equivalent mantra inside Bash, would
    probably be a good idea.  It could be even the same problem as with=20
4) Grep configuration issue - can't rebuild using config.bat, can build =
using pre-configured makefile
5) debugging
6) profiling
7) CTRL-C and CTRL-BREAK testing
8) programs that catch SIGPE and SIGINT
9) All the gotchas in section 3.3 of FAQ
10) Help out with crashes of latest RHIDE 1.4.7.9 that now "runs" under =
Win 2K (06-Aug-2001 release)
11) GCC 3.0.1 compile and test
12) Error 183 for testing if directories exist on Win2K  (check redirect =
to /dev/nul)
13) Investigate stat() to see if it retuns correct value (comopare =
against fstat())

(highest priority issue is #1, issue 1 & 2 really should be the same =
priority)

those opened with the old DOS APIs.)!!!!!

1) DPMI selector leaking is worse under Win 2K than WIn 9x. There are =
potention fixes for Win 9x and a QAD for Win 2K
    I have used the QAD Win 2K fix and it appears to work.

the crt0 & open.c patches.

Test info: BSP =3D Build Subsequent Packages
Build date info:
    W98 - package built on Win98 and used on Win2000
    W2K - package built and used on Win2K
    N/A - no executables, therefore no need to re-build at this point in =
time
    OTB - Out of the box - as downloaded from the WEB

Status:
    WIP - Work in progress (untested, but being used to build other =
packages)
    OK  - So far no issues found and tested
    BAD - Issues in package built
    NBY - Not built yet

WIN 2K PATCHES NEEDED FOR 2.03 TO WORK ON WIN 2K:
-------------------------------------------------
1) NTVDM patch :- NTVDM crashes if you nest DJGPP images (make/gcc/cc1).
    Solution 1 is to use the NTVDM patch from the CVS version of DJGPP
    library and rebuild everything.
2) Many bugs in the long file name support.
        open.c issue on redirection. - see below for more info.
3) crt0 SBRK patch:- Sometimes you may see crashes with descriptor =
limits 0x7xxxxxxx - this
   is the wrap bug.  You can patch an image built with DJGPP V2.03 to
   fix this using ftp://clio.rice.edu/djgpp/ntsbrkpat.zip
   Name - crt0 patch
4) djdir patch :- _open.c & _create.c  - DJDIR environment variables
5) utime patch :- utime.c patch for touch & cp setting time of a file=20
6) rename patch :- _rename patch. W2K reports a strange error code when =
you try rename a file into a
name that's already taken, and that confuses _rename's logic.
7) fstat.c patch :- Use 0x71A6 call on NT/2000/XP so read only bit not =
set\
8) WIP - link.c :- use stat or fstat - don't use either

PATCHES TO GET DJGPP WORKING ON W2K, BUT DEBATEABLE IF IT IS A VALID FIX
------------------------------------------------------------------------
A) open.c patch do not exit if write of a file with zero bytes fail

the functions work or have been tested!!
