Hi Andreas,

thanks for having a look on it.

a) which version of clang are you using?
`clang -v`output:

Debian clang version 11.0.1-2
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
Found candidate GCC installation: /usr/bin/../lib/gcc/x86_64-linux-gnu/10

I _think_ gnustep-2.0, because I have this in my GNUmakefile:

ADDITIONAL_FLAGS += -fobjc-runtime=gnustep-2.0

and this in ~/.bashrc:

export RUNTIME_VERSION=gnustep-2.0

I do not specify anything and thus assume it the one defined in ~/.bashrc:

export LD=/usr/bin/ld.gold

Debian 11
