[Buildroot] Fwd: g++-target compilation error

[Sergey Naumov]

Slight correction: remaking does not help. After 10 minutes of
compilation it returns the same error.

Hello.

While compiling toolchain with "keep development files" on,
compilation terminated for gcc-4.4.5-target while compiling
i586-unknown-linux-uclibc/bits/sdtr1c++.h.gch/O2g.gch
with errors gcc-4.4.5-target/i586-unknown-linux-uclibc/libstdc++-v3/include/tr1_impl/cfenv:49
error: `::fenv_t` has not been declared and a few similar errors. Then
I run make again to get the errors into a file, but compilation
proceeds normally.

Is it buildroot bug or some gcc libstdc++ unavoidable "feature"? Once
I have tried to make a toolchain from scratch with gcc-4.5.1 and
eglibc and encountered similar error: compilation terminated at
libstdc++ stage, but executing make once more helped.
