Oh of course this makes sense.

Nothing unfortunate just something I did not consider. What happens with:

echo “” | LC_ALL= gcc -xc -E -v -

?

It is matter of forcing gcc in the script into English so markers in the script
can be searched for.

That is expected. The gdb config script in the RSB knows how to find the python
major and minor version numbers and then to inspect this directory.
