Ok, thank you. In order to get around the restriction that global must always 
be run in a project, I'm using the following hack for now:

/usr/bin/global "$@" 2> /dev/null || (cd $global_home; /usr/bin/global -a "$@")

$global_home is a dummy project with one empty file called dummy.c (a dummy 
project with no files at all does not work).

Suggestion: if there are other users like me who expect this behaviour, you 
could consider changing the behaviour + documentation of GTAGSLIBPATH from 

----- Existing -----
GTAGSLIBPATH
       If this variable is set, it is used as the path  to  search  for
       library  functions.  If  the  given  symbol  is not found in the
       project, global  also  searches  in  these  paths.   Since  only
       ´GTAGS´  is  targeted in the retrieval, this variable is ignored
       when -r or -s is specified.
---------------------------------------------------------------------------

----- Suggested -----
GTAGSLIBPATH
       If this variable is set, it is used as the path to search for
       library functions. If the given symbol is not found in the CURRENT
       project, OR IF GLOBAL IS NOT BEING RUN FROM WITHIN ANY PROJECT,
       global also searches in these paths. Since only ´GTAGS´ is
       targeted in the retrieval, this variable is ignored when -r or -s
       is specified.

Thanks again,
