I communicated with the gcc people about the problem with tanh.

A very helpful exchange.

libstdc++ tanh functions call gcc __builtin_xxx functions, which just
call the respective libm code.  This was not clear to me in `info gcc`

Ubuntu 9.10 uses eglibc, which is a somewhat "enhanced??" version of
glibc.  I think the math functions are the same.  math/s_ctanhl.c is the
same in both.

I cannot build either glibc or eglibc on my ubuntu 9.10!
