------- Comment #18 from armand dot potter at free dot fr  2009-12-19 15:44 -------
Configure is as follow:

/tmp/gcc-4.4.2/configure --enable-shared --enable-clocale=gnu

--target=x86_64-mine-linux-gnu

Here is the error:

/new-system being the sysroot dir used by gcc and where target glibc headers
are. Adding "-I/usr/include" also works even if wrong header is picked this
time:

  using ::fenv_t;
# 47 "/tmp/gcc-build/x86_64-mine-linux-gnu/libstdc++-v3/include/tr1/cfenv" 2 3

As a side note changing the "C" header model from c_global to c_std in
libstdc++-v3/configure.host file solves the problem as fenv.h is no longer
installed by gcc along with three other headers (two of them being also
provided by glibc).

Thanks for your time.
