All, Sorry, I've been busy these last days...

It was intended to fix an issue with searching for C++ headers, and fixed the issue seen by Anthony [2]. But I'd be glad to revert it, so we can add a proper fix. > "${CT_SYSROOT_DIR}/usr/include" is "${CT_HEADERS_DIR}" where the libc > is told to install its headers... > As the GCC's fenv.h tries to include the one provided by the C > library, it naturally dies. I see. So, rather than tell gcc where to install its C++ headers, we should find a way how to find them. After it itself installed them in the first place. In the end it boils down to: "do we really want everything in the sysroot?" The build-time symlink include to sysroot/usr/include was meant as a way to have everything related to the target system lie in the sysroot. But that does not seem to be easily done...
