I'm considering using manywarnings in m4, and noticed that newer gcc
supports even more warnings. I noticed several warnings supported by gcc
4.3.4 --help=warnings that were not listed already; see the patch below.
However, looking at it closer, it is obvious that some of the newly-added
warnings added in this patch are C++ or ObjC-specific; maybe we should
break this macro into the set of warnings useful for each language, rather
than an overall list. For that matter, some warnings (like -Wtraditional)
don't make any sense in the context of gnulib, since we require C89 or
better, so including them in gl_MANYWARN_ALL_GCC just means that package
maintainers have to exclude it.
