Fail during bootstrap on the --g -O2 pch

[Ed Smith-Rowland <3dw4rd at verizon dot net>]

All,

I'm trying to bootstrap my tr1 special functions patch in shape for 
people to look at it.

The compile bombs out when building the pre-compiled headers.
It seems to get the O0g.gch but compile fails on O2g.gch.

Is std::tr1::copysign not available at -O2 -g but is OK at -O0 -g?

Here is the end:

==============================================================================

I'm going to try to reproduce this on a gcc-4.1.1 with a smaller test case.

Meanwhile, I got bessel_function.tcc to work with ::copysign instead of 
std::tr1::copysign.
It failed with both std::tr1::copysign and std::copysign.

I will send out a tarball patch next after the bootstrap finishes.

BTW, this is MacOSX 10.3.9.
