libs don't compile without warnings

[Fabian Maurer]

Hello,

The integrated libraries under libs don't compile without warnings.
Is there a way to suppress those warnings, but keep the ones from normal wine
files? I'd like to compile wine with Werror, and fix the warnings we have, but
this makes it impossible.

Regards,
Fabian Maurer

What are you compiling with? With "current" debian testing tools, 
including mingw-w64, I don't get compilation warnings.

That's probably because I compile with -Wall. There's for example a lot unused
variable/function and format string errors.

My gcc/mingw version is 11.2.0 (Arch Linux)

That's probably because third-party libs are built without Wine warning 
flags, but not without user-specified warning flags. You will probably 
have to change something in makedep.c to make sure user warnings are 
filtered out there too, or add -Wall / -Werror to Wine warnings in 
configure.ac instead.

Ah, seems I was wrong, there is no need for -Wall, since Wine uses that per 
default already. Thanks for pointing me the right way, it's part of 
EXTRACFLAGS.

Though that means that my warnings/errors are not due to additional flags.
For completeness, attaching a patch that shows all the warnings I god.
It's a bunch of "might not be initialized" and three cases of "string 
overflow".

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?
