@c INTERNALS is used by md.texi to determine whether to include the
@c whole of that file, in the internals manual, or only the part
@c dealing with constraints, in the user manual.

@c NOTE: checks/things to do:
@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

This manual documents how to use the GNU compilers,
as well as their features and incompatibilities, and how to report
bugs.  It corresponds to the compilers

The internals of the GNU compilers, including how to port them to new
targets and some information about how to write front ends for new
languages, are documented in a separate manual.  @xref{Top,,

@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.
