# Configure flag notes:
#  1. The thread C++ library cannot be built, as the thread C library
#     was not build in stage1-gcc.
#  2. Prevents the installation of precompiled include files, which are
#     not needed at this stage.
#  3. From LFS: the header location of C++ needs to be explicitly given
#     as we are running the configure script from the top-level
#     directory.
