Problem with fccompat for Windows 64bit

I have problem compiling ffmpeg. This library has many plugins including fontconfig. https://github.com/Jamaika1/plugins_ffmpeg_vvc_evc_htj2k I use gcc 11.3.1 under Windows. I don't use POSIX. I'm leaving aside the fact why I don't use MSVC but some gcc. I managed to create librsvg (c) {glib, libxml2, cairo, pango, croco, harfbuzz, libffi, lzma, pixman, fribidi, freetype, fonconfig} Not everything is compatible with each other but it works only with pthread win32. http://msystem.waw.pl/x265/mingw-gcc1131-20221227.7z

Using built-in specs.
