Not possible to compile ffmpeg for 32-bit on mingw32

[AndersIgelstrom]

I am building ffmpeg/x264 on Windows 10.
Have built 64-bit successfully.
The 32-bit configuration gives
"Host Compiler lacks C11 support"

Gcc version is 14.2.0 and should have c11 from wah

This is how I set up the environment to compile.

Installed msys2-x86_64-20250221.exe
In the UCRT64 command window:

• pacman -S git
• pacman -S mingw-w64-i686-toolchain
• pacman -S mingw-w64-x86_64-toolchain
• pacman -S base-devel
• pacman -S yasm
• pacman -S nasm
• mkdir /src
• cd /src

In mingw32:

• git clone ​http://git.videolan.org/git/x264.git
• git clone ​https://git.ffmpeg.org/ffmpeg.git ffmpeg
• cd x264
• make clean
• ./configure --prefix=/mingw32 --enable-shared --disable-cli

--disable-gpl --enable-lto --host=i686-w64-mingw32

• make -j8
• make install
• cd ../ffmpeg
• As we have a license I edit ./configure: move libx264 from EXTERNAL_LIBRARY_GPL_LIST to EXTERNAL_LIBRARY_LIST
• make clean

./configure --prefix=/mingw32 --enable-shared --disable-static

--disable-programs --disable-lzma --disable-doc --disable-sdl2

--enable-libx264 --disable-debug --host=i686-w64-mingw32

Error:
"Host Compiler lacks C11 support"

ffmpeg version 7.1.1.1 and also from git March 15
built on Windows 10
