The <new> and <exception> headers each include each other, which makes building them as header-units "exciting". The <new> header only needs the definition of std::exception (in order to derive from it) which is already in its own header, so just include that. libstdc++-v3/ChangeLog: * include/bits/stl_iterator.h: Include <bits/exception_defines.h> for definitions of __try, __catch and __throw_exception_again. (counted_iterator::operator++(int)): Use __throw_exception_again instead of throw. * libsupc++/new: Include <bits/exception.h> not <exception>. * libsupc++/new_opvnt.cc: Include <bits/exception_defines.h>. * testsuite/18_support/destroying_delete.cc: Include <type_traits> for std::is_same_v definition. * testsuite/20_util/variant/index_type.cc: Qualify size_t.
