os_defines.h predates CPLUSCPLUS_CPP_SPEC by many moons; I don't think
anyone would have a problem with moving from one to the other en masse.
(Benjamin?)

Somebody once mentioned the possibility of having cc1plus always initially
include os_defines.h, period, for every compilation.  Thus _LARGEFILE_SOURCE
and whatnot would always be defined.  This would allow easier maintainance,
for one thing, compared to messing with specs.

A friend of mine implemented this, sortof, as a beginner's project.
It seems simple enough to do, but was breaking local builds, so we never
cleaned it up for submission.

Is this a viable idea?

Yes and yes.
