The globalrc file

Hello,

Am having trouble getting global to read and use .globalrc file.  Here 
are the steps:

   1) copied <install_dir>/share/gtags/gtags.conf to 
c:\home\suresh\.globalrc

   2) set GTAGSCONF=c:\home\suresh\.globalrc

   3) modified c:\home\suresh\.globalrc by adding 3 lines to specify 
GTAGSDBPATH, GTAGSFORCECPP, and GTAGSROOT as follows:

       gtags:\
           :GTAGSDBPATH=c\:\\tmp:\
           :GTAGSFORCECPP\
           :GTAGSROOT=c\:\\home\\suresh:\
           :tc=common:\
           :tc=builtin-parser:
       builtin-parser:\

   4) touch c:\tmp\GTAGS

   5) cd c:\tmp

   6) c:\tmp>c:\opt\global\bin\global.exe -p -v
      checking c:/tmp/GTAGS
      GTAGS found at 'c:/tmp/GTAGS'.

   7) cd c:\home\suresh

   8) c:\home\suresh>c:\opt\global\bin\global.exe -p -v
      checking c:/home/suresh/GTAGS
      checking c:/home/suresh/obj/GTAGS
      checking c:/home/GTAGS
      checking c:/home/obj/GTAGS
      checking c://GTAGS
      checking c://obj/GTAGS
      global: GTAGS not found.

    9) c:\home\suresh>c:\opt\global\bin\global.exe -p -v --gtagsconf 
.globalrc
       c:\opt\global\bin\global.exe: unrecognized option '--gtagsconf'
       Usage: global [-aCdEGilmnNqrsStTvx][-e] pattern
              global -c[diImNoOPrsT] prefix
              global -f[aCdlnqrsStvx][-L file-list] files
              global -g[aCEGilmnoOqStvVx][-L file-list][-e] pattern [files]
              global -I[aCilmnqStvx][-e] pattern
              global -P[aCEGilmnoOqStvVx][-e] pattern
              global -p[qrv]
              global -u[qv]

Questions:

(A) In step 8, why wasn't value of GTAGSDBPATH and GTAGSROOT specified 
in .globalrc files used?

(B) In step 9, why didn't global accept --gtagsconf option?

Thanks,
