It appears that -nostdinc also excludes GCC internal header directory (for
e.g. stdarg.h), which I didn't expect.
Does someone know a clean way to resolve this? A quick check at GCC
command-line options didn't reveal a way to explicitly include that
directory afterwards without knowing its path.
I.e. something similar to `gcc -print-file-name=libgcc.a`

The DRM opt-in fallacy: "Your data belongs to us. We will decide when (and
how) you may access your data; but nobody's threatening your freedom: we
still allow you to remove your data and not access it at all."
