Research direction
Start in src/numpy/dtype.cpp, where the LONGDOUBLE and 2 * LONGDOUBLE dtype definitions are mentioned. Run the libs/python/test/numpy/dtype.py test or the reported libs/python/test command and inspect the generated extension's symbol error. Done means the dtype test imports successfully without the undefined get_complex_dtype<256> reference.
Written by the indexing model from the issue text.
Description
In src/numpy/dtype.cpp, the definition of get_float_dtype < LONGDOUBLE > and get_complex_dtype < 2 * LONGDOUBLE > lacks BOOST_NUMPY_DECL.
