Subject: Invent a value for argv[0] if not present
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=d2795b92b02253a36cb7406fbaeabdef6d7caa19;p=libs%2Fcore.git

Invent a value for argv[0] if not present

Gdbserver seems to pass an empty argv[0], at least on Windows.  That
causes problems with the various get_*_dir functions.
