--- Comment #4 from Dmitry Gorbachev <d.g.gorbachev at gmail dot com> --- vtv_fail.h, vtv_malloc.h, vtv_map.h, vtv_rts.h, vtv_set.h, vtv_utils.h are installed to /usr/local/include. GCC is configured with "--enable-version-specific-runtime-libs" (and "--disable-bootstrap"). Host/target/build is i686-pc-linux-gnu.
