current requires include directory (/usr/include) updated.
If you want to update your 1.5_ALPHA to current, try make -n build in
the top of base directory and see what will be done.
Otherwise (you still want to remain 1.5_ALPHA), 1.88 is the wrong revision
to be compiled on 1.5 branch.  Use '-r netbsd-1-5' option in updating cvs.

This is only for the current tree, not for 1.5_ALPHA.

This is already pulled up to 1.5 branch.  However you still need make
includes in at least sys directory to header files updated.
