It avoids it at a very large cost, namely skipping all the files where
it's not possible to compile each arm of every #if on the machine being
used.  I do not think that's a solution, just a band-aid; for instance,
won't it prevent include optimization in every file that contains even
one #ifdef WIN32?  Or what about files in which there are #if blocks
that each define the same function, constant table, etc?

The right solution would involve testing each #if block under the
conditions in which it was *meant* to be compiled.
