Re: Gtags plugin fails at call to system function using vim 6.4

Sorry, I left out important info:
I am running using vim/gvim on Windows
XP professional.
The output (captured with redir) from
the first call to :Gtags is

Error detected while processing function
<SNR>7_RunGlobal:
line   72:
E40: Can't open errorfile C:\DOCUME~1\aavakian\LOCALS~1\Temp\VIA4EF.tmp
Error detected while processing function
<SNR>7_RunGlobal:
line   80:
E42: No Errors

The shell variable values (unchanged
from defaults):

nocscopetag

  cscopetagorder=0    joinspaces

Subject	Gtags plugin fails at call to system function using vim 6.4

This line in gtags.vim seems to be the
problem:

    let stuff = system(cmd
. '>' . tmpfile)

I am using vim/gvim version 6.4 and
ctags 5.5.4.
The tags file from ctags works just
fine.
If I use the global command from the
command line, its seems to work OK.
The problem is that in the above line,
stuff is set with the output of global,
but the tmpfile is not created, i.e.
the output redirection does not happen.
(I have determined this by running debug
and stepping through the :Gtags
function.) The result is a msg "No
errors" and an empty Errors list window
opens, even though the corresponding
global command produces output
when run from the command line.

I have experimented using the above
form of the system function, and it
does not redirect to the tmpfile. Looking
at the vim help for the system
function, it appears that the Gtags.vim
usage of redirection is not really
supported, instead it is showing use
of the vim 'shellredir' option and
and (unavailable?) {tmp} file. Here
are the lines from vim :help system:

         
      The command executed is constructed using
several options:
        'shell'
'shellcmdflag' 'shellxquote' {expr} 'shellredir' {tmp} 'shellxquote'
         
      ({tmp} is an automatically generated file
name).

So now I am stuck:
1. the Gtags usage of the system function
does not cause redirection,
2. the documented system function does
not seem to give access to the {tmp} output.

Should I try to modify function! s:RunGlobal(...)
to use the output in variable stuff?
Is there a way to get the output of
the command run by system into a known file?

Help!

Thanks in advance.
