| -- the otherwise undocumented debug switches that are also recognized. |

| -- Procedures to scan out binder 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 is encountered. |

| -- Takes a compiler switch which potentially is equivalent to more |
| -- that one simple switches and returns the equivalent list of simple |
| -- switches that are stored in an ALI file. Switches will be extended |
| -- if initially null or too short. Last indicates the index in Switches |
| -- of the last simple switch. Last is equal to zero, if it has been |
| -- determined that Switch_Chars is ill-formed or does not contain any |
| -- switch that should be stored in an ALI file. Otherwise, the list of |
| -- simple switches is Switches (Switches'First .. Last). |
| -- |
| -- Example: if Switch_Chars is equal to "-gnatAwue", then the list of |
| -- simple switches will have 3 components: -gnatA, -gnatwu, -gnatwe. |

| -- The String_Access components of Switches should not be deallocated: |
| -- they are shallow copies of components in a table in the body. |

| -- simple switches. It may be an empty array if it has been determined |
| -- that Switch_Chars is ill-formed or does not contain any switch that |
| -- should be stored in an ALI file. The String_Access components of the |
| -- returned value should not be deallocated. |
