I think that matches the current policy (10.2 Libraries: "therefore the
static version must not be compiled with the -fPIC flag"). I'm hesitant
to violate that policy, even if I generally welcome the move to PIE.

Also note that simgear well respects DEB_BUILD_MAINT_OPTIONS via
dpkg-buildflags. A simgear compiled with DEB_BUILD_MAINT_OPTIONS
including hardening=+pie will generate a PIE-enabled library. That in
turn allows compiling fgrun with the same options, leading to a
PIE-enabled executable.

Are you sure this tested against a re-built simgear?

Kind Regards
