@c (For FSF printing, turn on smallbook, comment out finalout below;
@c that is all that is needed.)

@c 6/27/96 FSF DO wants smallbook fmt for 1st bound edition.
@c @smallbook

@c i also commented out the finalout command, so if there *are* any
@c overfulls, you'll (hopefully) see the rectangle in the right hand
@c margin. -mew 15june93
@c @finalout

@c NOTE: checks/things to do:
@c
@c -have bob do a search in all seven files for "mew" (ideally --mew,
@c  but i may have forgotten the occasional "--"..).
@c     Just checked... all have `--'!  Bob 22Jul96
@c     Use this to search:   grep -n '\-\-mew' *.texi
@c -item/itemx, text after all (sub/sub)section titles, etc..
@c -consider putting the lists of options on pp 17--> etc in columns or
@c  some such.
@c -overfulls.  do a search for "mew" in the files, and you will see
@c   overfulls that i noted but could not deal with.
@c -have to add text:  beginning of chapter 8

@c anything else?                       --mew 10feb93

@c Makeinfo handles the above macro OK, TeX needs manual line breaks;
@c they get lost at some point in handling the macro.  But if @macro is

@c Use with @@smallbook.

@c Cause even numbered pages to be printed on the left hand side of
@c the page and odd numbered pages to be printed on the right hand
@c side of the page.  Using this, you can print on both sides of a
@c sheet of paper and have the text on the same part of the sheet.

@c The text on right hand pages is pushed towards the right hand
@c margin and the text on left hand pages is pushed toward the left
@c hand margin.

@node Option Index
@unnumbered Option Index

GCC's command line options are indexed here without any initial @samp{-}
or @samp{--}.  Where an option has both positive and negative forms
(such as @option{-f@var{option}} and @option{-fno-@var{option}}),
relevant entries in the manual are indexed under the most appropriate
form; it may sometimes be useful to look up both forms.
