Bug ID: 54263
           Summary: Build of 7.22 fails with mingw-w64 10.0 (multiple
                    symbol redefinitions)
           Product: Wine
           Version: 7.22
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs@winehq.org
          Reporter: ilg@livius.net
      Distribution: ---
I have severl build scripts that I use to create the wine-xpack distribution
(https://github.com/xpack-dev-tools/wine-xpack/), and I successfully compiled
6.17, 6.23 and 7.22 with gcc 11.3 & mingw-w64 9.0.
When I tried to build 7.22 with the latest gcc 12.2 & mingw-w64 10.0, I got
multiple redefinition errors, for symbols from the sprintf family.
For example:
/home/ilg/Work/wine-xpack.git/build/linux-x64/sources/wine-7.22/dlls/ntdll/printf.c:56:11:
error: redefinition of '_vsnprintf'

va_list args )

I patched ntdll/printf.c to omit the new definitions and the builds advanced,
but later failed in string.c with other set of multiple definitions, later in
wcstring.c, and so on.
I gave up and returned to the older toolchain.
Am I missing something when configuring the build, or the wine sources are not
yet updated for mingw-w64 10.0?
