Thanks, it's now in.

Looking back at the patch, it seems I forgot to post the c.opt part,
which simply removed the documentation that's now in options.texi.
Now attached.  I went ahead and installed this part too since it
seemed pretty obvious.

Will do ;)  (And thanks to Eric for volunteering to handle SPARC.)

- ; 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.  If you do not want this
- ; negative form and you want it to be automatically rejected, add
- ; RejectNegative to the second field.
- 
- ; The second field is a space-separated list of which parts of the
- ; compiler recognize the switch, as declared by "Language" entries.
- ; If the switch takes an argument, then you should also specify
- ; "Joined" and/or "Separate" to indicate where the argument can
- ; appear.  If a Joined argument can legitimately be omitted, specify
- ; "JoinedOrMissing" instead of "Joined".  If the argument to a switch
- ; is a non-negative integer, you can specify "UInteger" and the switch
- ; decoder will convert the argument for you, or complain to the user
- ; if the argument is invalid.  "Var(name,set)" creates an integer
- ; variable "name".  The variable is declared and initialized to value
- ; given by "Init(value)" (or zero if this property is not defined).
- ; When the option is passed to compiler, this variable is set to "set"
- ; if value passed through the flag is nonzero, !"set" if value is zero,
- ; or to value if "set" is omitted.  If "VarExists"  is specified, the
- ; declaration for the variable is not created.  If "Report" is specified,
- ; the flag is output with -fverbose-asm.
- 
- ; The third field is the help text to output with --help.  This is
- ; automatically line-wrapped on output.  Normally the switch is output
- ; automatically, with the help text on the right hand side of the
- ; output.  However, if the help text contains a tab character, the
- ; text to the left of the tab is output instead of the switch, and the
- ; text to its right forms the help.  This is useful for elaborating on
- ; what type of argument a switch takes, for example.  If the second
- ; field contains "Undocumented" then nothing is output with --help.
- ; Only do this with good reason like the switch being internal between
- ; the driver and the front end - it is not an excuse to leave a switch
- ; undocumented.
- 
- ; 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.
