That would not help, because it is the call of global which failed, not
setting the environment variable. Thus executing gtags-find-tag, or any othe
function calling global, fails.

Maybe, but I seldom start xemacs. I open it on Monday morning and exit it on
Friday evening ;-) (as long as windows allows me for this).
Furthermore, I do not have one single project in a single directory, but
mostly have to switch between several.

Thanks. I already had luck by finding a solution (workaround). It works this
way:

        1. I have a batch file (global.bat) that calls global.exe with (almost) 
all
arguments.
        2. I have a patched gtags.el to use a variable gtags-cmd-global, which 
can
be set to global on "good" systems and to global.bat on windoows systems.

I attached both files to this mail in case others have the same problem.
Maybe you adapt the path to gtags.el?

Still I wonder why the direct call to global.exe fails. Maybe this is
related to djgpp or xemacs. Or does global play with stdout? I may examine
that...

Kind regards,
Frank
