There's a test.sh within, but pasting it inline:
```
gcc \
        -O1 -flto=1 \
        -o meson-generated_cython_special.c.o \
        -c meson-generated_cython_special.c.i

g++ \
        -fvisibility=hidden -O1 -flto=1 \
        -o special_wrappers.cpp.o \
        -c special_wrappers.cpp.ii

g++ \
        -O1 -flto=1 -shared \
        -o /dev/null \
        meson-generated_cython_special.c.o \
        special_wrappers.cpp.o > gcc_out.txt 2>&1
```
