-- Procedures to scan out front end switches stored in the given string.
-- The first character is known to be a valid switch character, and there
-- are no blanks or other switch terminator characters in the string, so
-- the entire string should consist of valid switch characters, except that
-- an optional terminating NUL character is allowed. A bad switch causes
-- a fatal error exit and control does not return. The call also sets
-- Usage_Requested to True if a switch -gnath is encountered.
-- Args is the full list of command line arguments. Arg_Rank is the
-- position of the switch in Args. It is used for certain switches -gnatx
-- to check if a subsequent switch -gnat-x cancels the switch -gnatx.
