error: there are no arguments to 'BOOST_STATIC_ASSERT' that depend on a template parameter, so a declaration of 'BOOST_STATIC_ASSERT' must be available [-fpermissive]

Trying to package boost.heap for Bazel Central Registry for 1.88.0 I get this:

external/boost.heap~/include/boost/heap/detail/tree_iterator.hpp: In constructor 'boost::heap::detail::tree_iterator<Node, ValueType, Alloc, ValueExtractor, PointerExtractor, check_null_pointer, ordered_iterator, ValueCompare>::tree_iterator(NodePointerIterator, NodePointerIterator, const Node*, const ValueCompare&)':
external/boost.heap~/include/boost/heap/detail/tree_iterator.hpp:198:9: error: there are no arguments to 'BOOST_STATIC_ASSERT' that depend on a template parameter, so a declaration of 'BOOST_STATIC_ASSERT' must be available [-fpermissive]
  198 |         BOOST_STATIC_ASSERT( ordered_iterator );
      |         ^~~~~~~~~~~~~~~~~~~
external/boost.heap~/include/boost/heap/detail/tree_iterator.hpp:198:9: note: (if you use '-fpermissive', G++ will accept your code, but allowing the use of an undeclared name is deprecated)

Bazel Central Registry builds are set up to check that each header compiles standalone, and for 1.87.0 this worked. For 1.88.0 there seems to be this new error. I would guess it is simply a missing include in include/boost/heap/detail/tree_iterator.hpp.

note that this is a rather strict policy: headers in detail are internal headers, that users should not include.
