Not just the gcc version, but _how_ the function is declared. 'static
inline' is okay, 'extern inline' without a later body is where you run
into problems. The bug exists in older libnl headers, and has been
fixed upstream for libnl3; but while Fedora 17 ships libnl with a
F17 actually has two different headers - one for libnl-1.1 (which
doesn't declare it inline) and one for libnl-3 (which does). Apparently
Ubuntu 10.0.4 is somewhere in between.
patched header, Ubuntu 10.04 did not.
