suggested compile warnings

["Theodore A. Roth" <troth@openavr.org>]

Hi,

I've always been configuring gdb with --enable-gdb-build-warnings=-Werror
and thought that there where a bunch of gcc compile warnings issued.
Looking more closely at my builds, that doesn't seem to be true.

For my own apps, I like to use '-Wall -Werror' as it lets the compiler
catch a lot of my stupid mistakes. I tried '-Wall -Werror' for gdb,
but that seems to be too restrictive for gdb source.

Does anyone else compile gdb with any of the -W<foo> gcc options?
Is there a recommended list of these which should be used?

For example, adding -Wunused (without -Werror), turns up 149 wanrings.
Most are unused variables, some are static decl's for functions that
aren't defined. Most if not all of these should be trivial to fix.
