I see no obvious reason for PCH issues connected with my patch or this fix 
- I'd expect PCH to care only at most about whether the predefined macros 
are consistent between different compilations for which they should be 
consistent, not whether they are correct - but I suppose that if whether 
flag_excess_precision was initialized at the relevant time depended on 
compiler options, that could have resulted in an inconsistency affecting 
PCH.
