Yes, that works correctly on glibc.

Almost forgot about Hurd there :)
And older versions of glibc run on some other Unixes too.

Yes, that would work, but we would need a configure macro to test for
kernel types, like an AC_GROK_KERNEL_TYPE. Then it could test for
u_int32_t etc, and __u32 etc, so bits.c could specify the correct one. 
The macro would need to know what kernel headers to include for the test,
though. Is this what KERNEL_HDRS is for?

Same here as with the typedefs. AC_EGREP_CPP would work if the test knew
which kernel headers to include.
