Bug ID: 51794
           Summary: Implement wineclang - a wrapper around clang to build
                    software with winelib
           Product: Wine
           Version: 6.17
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winelib
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

A user should be able to configure which stock clang (i.e. one default in the
distro, or the latest one from the official repos) and which MinGW target and
which sysroot to use. I.e. if I have a CMake toolchain file for
cross-compilation for Windows 64-bit with clang-14 using MinGW-w64 stdlib
installed from Ubuntu packages, then I should be able to just slightly modify
it in order to get native compilation via wine-gcc the following way:

1. replace clang compilers with wineclang
2. provide wineclang with arguments pointing to real clang binaries I want to
use.

Probably it should be unified with winegcc/wineg++ and renamed into
winecompiler, which should be symlinked to
winegcc/wineg++/wineclang/wineclang++.
