| -- 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. |
