   A good starting point would be fixing the code that chokes on
   -Wpointer-sign :-)
   I just arbitrarily checked sbin/newfs_sysvbfs and it doesn't appear
   there's any reason to keep the -Wno-pointer-sign; it compiles cleanly
   without it using both -fsigned-char and -funsigned-char.
   Maybe after 5.0 is branched someone (probably me) should go through
   that list and clean out the special cases that are no longer required.

that would be cool.  doc/HACKS should document these as well as grep -r.
