Because it _ain't_ PC-specific.  It's ISA-bus-specific and
PCI-bus-specific, and at least two ports exist that have ISA and PCI
busses (i386 and alpha).

This sounds as though you didn't update your compiler binaries.  Make
sure the running compiler was built from sources from the same sup as
the kernel source tree you're trying to build.
