Today's source cannot build on NetBSD

Which is fine, and probably the correct thing for the master copy in 
/usr/src/sys/arch/xxx/include/ansi.h.

It won't matter.  When/if gcc is integrated into the netbsd sources, you 
won't run fixincludes there because you can fix your header files.  When 
gcc is used as a stand-alone package any files it needs to be fixed will 
be squirrelled away in its own private install tree.  Other compilers will 
never see the changes.  So if fixincludes fails to spot the above 
workaround (and I don't think it does), it won't matter anyway, since it 
will never be see by anything that doesn't require the fix anyway.
