I am having some problems with patch and redir.. Lets see if I can't
make even Eli happy today ;-)

Well general.. win95 servicpack 1, .. uhm djgpp works wonderfully,
last virusscan (yesterday) found no viruses..  (mcafee scan, february
data-file.) Haven't tried it under plain dos. Tried it both under bash
and 4dos as my shell.

First of all c:\temp exists, the TMPDIR variable in djgpp.env file
points there. At the start it is empty except for the tmp-subdir.

** Patch weirdness ********************

d:\tst>patch -p2 < diffs-t6
Hmm...  Looks like a unified diff to me...
The text leading up to this was:
--------------------------
|--- port/bash-1.14.7/mm        Mon Dec 30 18:29:38 1996
|+++ tmp/bash-1.14.7/mm Sat Mar  1 21:39:50 1997
--------------------------
Patching file mm using Plan A...
Hunk #1 succeeded at 1.
Can't backup mm, output is in c:/temp/poaaaaaa: No such file or directory (ENOENT)
done

d:\tst>dir c:\temp

 Volume in drive C is ANDYS C        Serial number is 1C73:8081
 Directory of  C:\temp\*

         1,016 bytes in 2 files and 3 dirs    16,384 bytes allocated
    84,484,096 bytes free

Hmm the files above seems to contain the information I am looking
for.. (the files patched)

** PATCH + REDIR weirdness ********************

Ok. lets try some magic.. 

d:\tst>redir -eo patch -p2 < diffs-t6 > outfile
d:\tst>cat diffs-t6 | redir -eo patch -p2 > outfile

Tells me tht 4dos has performed an illegal operation and will be
terminated.. unspecified exception, fault location 0000:00E.

d:\tst>cat diffs-t6 | redir -eo patch -p2 
Just closes the window.. 

And I have a outputfile with lengt 0

Trying redir for other purposes.. 
d:\tst>redir -eo gcc --version
2.7.2.1

Works.. 

** Versions ********************

d:/tst: ls -l h:/djgpp/bin/patch.exe
-rwxr-xr-x   1 flognat  dos        117248 Oct 19 11:28 h:/djgpp/bin/patch.exe*
No more patch.exe found in the vicinity.. 

d:/tst: ls -l h:/djgpp/bin/redir.exe
-rwxr-xr-x   1 flognat  dos         60416 Jan 13 22:08 h:/djgpp/bin/redir.exe*
                                          ^^^^^^^^^^^^ hmm weird date, but 
                                                       the size is the same as
                                                       at delories site.. 

Uhm oh.. my go32.v2 sayz.. 

go32/v2 version 2.0 built Aug 12 1996 22:27:23
Usage: go32 coff-image [args]
Rename this to go32.exe only if you need a go32 that can run v2 binaries as
 well as v1 binaries (old makefiles).  Put ahead of the old go32 in your PATH
 but do not delete your old go32 - leave it in the PATH after this one.
Set GO32_V2_DEBUG=y in the environment to get verbose output.
