Description: upstream: workaround: __int128__ ill-fallback on 32bit arch
 Workaround for a compile time issue due to a ill-fallback by PCG of the
 __int128__ type as supported by GCC on 64bit arch
 (see src/pcg-cpp/include/pcg_uint128.hpp).
 However this patch is useless since the building fails at link time due
 to architecture limitations on 32bit arch.
 Meant to be submitted for the record to the upstream maintainer.
