Actually, the customer who uses b.out is the same customer that's
paying us for PCHs.  You can imagine that if we had to take out b.out
support in C++ to make PCHs work, they wouldn't think that was very
useful---and if we insisted that this is what they were getting,
they'd probably think twice before funding any such work again.

I would think that the GCC group should encourage such customers.
Without this project, the integrated preprocessor would still be
`experimental', and precompiled headers wouldn't even be in the design
phase (instead in the nearly-ready-to-contribute phase).
