; This file is processed by the script opts.sh. It is a database of
; command line options, with each record separated by a blank line,
; and each field appearing on its own line. The first field is the
; command-line switch with the leading "-" removed. All options
; beginning with "f" or "W" are implicitly assumed to take a "no-"
; form; this form should not be listed.
; The second field is a space-separated list of which parts of the
; compiler recognize the switch. Current valid entries are "C",
; "ObjC", "C++" and "ObjC++". If the switch takes an argument, then
; you should also specify "Joined" and/or "Separate" to indicate where
; the argument can appear.
; Comments can appear on their own line anwhere in the file, preceded
; by a semicolon. Whitespace is permitted before the semicolon.
; For each switch XXX below, an enumeration constant is created by the
; script opts.sh spelt OPT_XXX, but with all non-alphanumeric
; characters replaced with an underscore.
; Please try to keep this file in ASCII collating order.
