does #pragma GCC optimize work with gcc 4.9.2 LTO?

[starlight.2014q4@binnacle.cx]

In the absence of a response and after
some digging, I decided the answer to the
query is "no".

So the small amount of -O3 code was moved
into separate modules and compiled
without -flto.  This seems to produce
the best of both--all sorts of whole-
program optimization for the bulk of
the -O2 code, and aggressive 
optimization for the bits that benefit
from it.
