[gps-users] problem when building body

[jf Menon]

Hello,

I have downloaded the 2.1.0 version of gps.
I make a "spec" file, and here is what I get when I use the menu: 
Edit->Generate Body

unrecognized switch: /users
unrecognized switch: /mpup371
unrecognized switch: /ada
unrecognized switch: /adago
unrecognized switch: /adago.gpr
unrecognized switch: /users
unrecognized switch: /mpup371
unrecognized switch: /ada
unrecognized switch: /adago
unrecognized switch: /sgf.ads
unrecognized switch: /users
unrecognized switch: /mpup371
unrecognized switch: /ada
unrecognized switch: /adago
ambiguous switch: / (matches 
/CURRENT_DIRECTORY,/NOCURRENT_DIRECTORY,/FULL,/NOFULL,/HEADER,/INDENTATION,/LINE_LENGTH,/QUIET,/NOQUIET,/SEARCH,/TREE_FILE,/VERBOSE,/NOVERBOSE)


what is the problem ?

thx
