MINGW-packages: [SDL2_ttf] Missing C++ symbols statically linked with C

Description / Steps to reproduce the issue

When statically linking “SDL2_ttf” in a C project, the linker throws errors for missing symbols. This can be worked around by including “stdlibc++”, but this shouldn’t be required?

Minimal reproduction

main.c;

#include <SDL2/SDL.h>
#include <SDL2/SDL_ttf.h>

int main(int argc, char *argv[]) {
    TTF_Font* font = TTF_OpenFontRW(SDL_RWFromConstMem(NULL, 0), 1, 16);
    TTF_SetFontStyle(font, TTF_STYLE_NORMAL);
    return 0;
}

meson.build:

project('example', 'c', version: '1.0.0')
executable(
    'example', ['main.c'],
    dependencies: [
        dependency('sdl2', static: true),
        dependency('sdl2_ttf', static: true)
    ]
)

Expected behavior

The project is successfully linked.

Actual behavior

The linker throws an error for missing “stdlibc++” symbols.
