[-- Warning: decoded text below may be mangled, UTF-8 assumed --]
[-- Attachment #1: Type: text/plain, Size: 980 bytes --]

I want to un-show a specific warning, namely the one about string length:
"Warnung: Zeichenkettenlänge »5388« ist größer als die Länge »509«, die von
ISO-C89-Compilern unterstützt werden muss" (which translates roughly to
"Warning: String length »5388« is larger than the length »509« which is required
to be supported by ISO-C89 compilers"). The documentation on
http://gcc.gnu.org/onlinedocs/gcc-3.3.5/gcc/Warning-Options.html#Warning-Options
does show how to do this.

Please note that I'm quite happy with all other warnings.

That is because there is no support yet, see PR 9049 which I am closing this as a dup of.

I don't want to exclude warnings for a specific part of the code, but a specific
warning for all code.

You can use that to disable this warning for all sources by putting a #pragma in a header that gets 
included.  There is no way to disable this warning at all (I assume you are using -pedantic since that is 
only when this warning gets enabled as C90 says you only have support up to certain length of strings 
constants).

That would be a workaround, not a solution. What I'm looking for is
-Wno-string-length.

I think it should be possible to diable any warning. Since you seem to see
-pedantic as one big heap I'll make this a feature request.

------- Comment #6 from pinskia at gcc dot gnu dot org  2006-01-29 03:34 -------
The options in 4.2.0 is "-Woverlength-strings"
Fixed by:
        * c.opt: Add -W(no-)overlength-strings.
        * doc/invoke.texi: Document it.
        * c-opts.c (c_common_handle_option): -pedantic implies
        -Woverlength-strings, if not explicitly disabled already.
        (c_common_post_options): -Woverlength-strings defaults to off, and
        is always off for C++.
        * c-common.c (fix_string_type): Issue warning about strings longer
        than is portable only if warn_overlength_strings.  Rearrange code
        a little for clarity.
        * configure.in: Check for -Wno-overlength-strings as well before
        enabling -pedantic in stage 1.
        * Makefile.in (STRICT2_WARN): Add -Wno-overlength-strings.
        (gcc.o-warn, insn-automata.o-warn, build/gencondmd.o-warn): Delete.
