gdb: enable -Wmissing-prototypes warning
Commit Message
While compiling with clang, I noticed it didn't catch cases where my
function declaration didn't match my function definition. This is
normally caught by gcc with -Wmissing-declarations.
On clang, this is caught by -Wmissing-prototypes instead.
Note that on gcc, -Wmissing-prototypes also exists, but is only valid
for C and Objective-C. It gets correctly rejected by the configure
script since gcc rejects it with:
cc1plus: error: command line option '-Wmissing-prototypes' is valid for C/ObjC but not for C++ -Werror
So this warning flag ends up not used for gcc (which is what we want).
gdb/ChangeLog:
* configure: Re-generate.
gdbserver/ChangeLog:
* configure: Re-generate.
gdbsupport/ChangeLog:
* configure: Re-generate.
* warning.m4: Enable -Wmissing-prototypes.
