`--disable-nls'
The `--enable-nls' option enables Native Language Support
(NLS), which lets GCC output diagnostics in languages other
- than American English. No translations are available yet, so
- the main users of this option now are those translating GCC's
- diagnostics who want to test their work. Once translations
- become available, Native Language Support will become enabled
- by default. The `--disable-nls' option disables NLS.

`--with-included-gettext'
- If NLS is enabled, the GCC build procedure normally attempts
- to use the host's `gettext' libraries, and falls back on
- GCC's copy of the GNU `gettext' library only if the host
- libraries do not suffice. The `--with-included-gettext'
- option causes the build procedure to prefer its copy of GNU
- `gettext'.

+ the build procedure to prefer its copy of GNU `gettext'. This
+ is the default. If you want the GCC build procedure to prefer
+ the host's `gettext' libraries, use
+ `--without-included-gettext'.
`--with-catgets'
If NLS is enabled, and if the host lacks `gettext' but has the
`gettext' library. The `--with-catgets' option causes the
build procedure to use the host's `catgets' in this situation.
+ `--enable-maintainer-mode'
+ The build rules that regenerate the GCC master message catalog
+ `gcc.pot' are normally disabled. This is because it can only
+ be rebuilt if the complete source tree is present. If you
+ have changed the sources and want to rebuild the catalog,
+ configuring with `--enable-maintainer-mode' will enable this.
+ Note that you need a special version of the `gettext' tools
+ to do so.

- Under Irix 6, if you are using Irix `cc' as your bootstrap
- compiler, you must ensure that the N32 ABI is in use. To test
- this, compile a simple C file with `cc' and then run `file'
- on the resulting object file. The output should look like:
-
- test.o: ELF N32 MSB ...
-
- If you see:
-
- test.o: ELF 32-bit MSB
-
- then your version of `cc' uses the O32 ABI default. You should
- set the environment variable `CC' to `cc -n32' before configuring
- GCC.
