htags -d not working?

[Rui Lopes]

Hello,

I'm trying to generate the G* and HTML files under a directory separated 
from the main sourcecode tree using htags (from GLOBAL 4.8) like this:

$ cd $SRCDIR && htags -d $TAGSDIR $TAGSDIR
but it fails with:
htags: GTAGS not found.

Which seems a bug.  I had to use:

$ export GTAGSROOT=$SRCDIR
$ export GTAGSDBPATH=$TAGSDIR
$ cd $SRCDIR && htags $TAGSDIR


Best regards,
Rui Lopes
