-------
I'm using about the same configuration (cross-LFS build but with gcc 4.4.2) and
got the same error. I did some investigations and the problem is that fenv.h
file from build tree is first included (and defines _GLIBCXX_FENV_H to 1) and
then include_next includes fenv.h from host (installed in
/usr/TARGET/include/c++/VERSION/fenv.h) and this time as _GLIBCXX_FENV_H is
already defined, does nothing so fenv.h from glibc is never included.
For a native build, just compiled c++ compiler is used with the -nostdinc++
flag so that /usr/TARGET/include/c++/VERSION/fenv.h is not seen and
include_next works as expected including glibc header.
I don't know what is the correct solution but at least you know what the real
problem is.
