-
-- If a variable has a value of "m" in the previous .config file,
-  and a type of bool in the Config script, then all the interpreters
-  get confused.  This happens frequently when someone changes a
-  tristate option to a bool option and people in the field have
-  .config files with a value of 'm'.  For example: CONFIG_PSMOUSE.
-
-- CONFIG_MODVERSIONS has incorrect dependencies.  If you have a
-  problem building the kernel, and you have CONFIG_MODVERSIONS turned
-  on, do a 'make dep' followed by 'make clean' before you try anything
-  else.
-
-- 'make dep' uses multistage dependencies, so the .hdepend file contains
-  'touch' commands.  As a result, building a kernel often touches files
-  in include/linux/*.h.  This messes up CVS and other systems which like
-  to rely on file dates.
-
-- 'make dep' fails for C files which include other C files, such as
-  drivers/cdrom/sbpcd2.c.
