--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
GCC and LLVM are known to implement the language extension of bitfields larger
than int differently and this is one of the expected results.
GCC does _not_ promote such bitfields and thus the negation is carried out
in 'unsigned long : 37' and then zero-extended to long int.
