Does someone know a clean way to resolve this? A quick check at GCC command-line options didn't reveal a way to explicitly include that directory afterwards without knowing its path. I.e. something similar to `gcc -print-file-name=libgcc.a` On Thu, Oct 29, 2009 at 12:16:23AM +0100, Robert Millan wrote: > > Committed then. > > On Mon, Oct 26, 2009 at 05:16:38PM +0100, Robert Millan wrote: > > > > It should be pretty obvious that we don't want to use system headers when > > building target, but we've been for so long without this flag that I want > > to make sure. > > > > Does anyone see a problem with it? > > > > -- > > Robert Millan > > > > The DRM opt-in fallacy: "Your data belongs to us.
