FYI: DMD has been using -fPIC by default on Linux x86_64 since 2.072.2 too:

https://github.com/dlang/dmd/pull/6359

It's just that the Makefile scripts in dmd, druntime and phobos reset the predefined flags with `-conf=` (aka the backdoor) and thus a lot of manual updating was required.

I will look into backporting these changes to dmd-cxx to see if that resolves the issues i was having.

Thanks guys for all you help.
