Xaw3d-1.5 had these enabled via a sed line that uncommented EXTRA_DEFINES. In -1.6, this is replaced by the configure options --enable-arrow-scrollbars --enable-gray-stipples You might also consider --enable-multiplane-bitmaps, which introduces a dependency. See ./configure --help and configure.ac Reproducible: Always A workaround for users: (might require portage 2.2) Create /etc/portage/env/xaw3d.conf with EXTRA_ECONF="--enable-arrow-scrollbars --enable-gray-stipples" Create /etc/portage/package.env with >=x11-libs/libXaw3d-1.6 xaw3d.conf then recompile.
Thanks! Done. I didn't add --enable-multiplane-bitmaps since it adds a dependency and 1.6.2 is already marked stable on some architectures.
