Perhaps. The problem I see is that -fsyntax-only implies that the
compiler is not doing any analysis/optimization/codegen, which is not
the case with -fwpa. Having flag_syntax_only set has other
side-effects that may get in the way with what we want to do in WPA.
I don't really mind one way or the other.
