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

+   --  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

+   --  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
