All 6 case-sensitivity shim headers in tools/linux/overlay/include/
now use #include_next instead of #include to forward to the real
MinGW system header, avoiding infinite preprocessor recursion on
Linux (Debian/WSL) where overlay/include is first in the search path.
Fixes build failures on Debian WSL (GCC 12) for all configurations.
Also update nsis7z.dll binaries built with the fixed overlay.
Cross-compiled from Linux using MinGW-w64 via the new overlay build
infrastructure. All three targets built clean (Exit Code 0):
- plugins/x86-ansi/nsis7z.dll (i686, non-unicode)
- plugins/x86-unicode/nsis7z.dll (i686, unicode)
- plugins/amd64-unicode/nsis7z.dll (x86_64, unicode)
- Implemented plugin API in `pluginapi.cpp` and `pluginapi.h` for NSIS integration.
- Added resource files `resource.h` and `resource.rc` for versioning and resource management.
- Created `ExtractCallbackConsole` class to handle extraction progress and user input.
- Developed main extraction logic in `Main.cpp` and `MainAr.cpp` for handling archives.
- Introduced user input utilities in `UserInputUtils2.cpp` and `UserInputUtils2.h` for password handling and user prompts.
- Added break signal handling in `NSISBreak.cpp` and `NSISBreak.h` for graceful interruption of extraction processes.
- Included standard header `StdAfx.h` for precompiled headers and common includes.
