  kconfig: use the file's name of sourced file
  kconfig: constify file name
  kconfig: don't emit warning upon rootmenu's prompt redefinition
  kconfig: replace KERNELVERSION usage by the mainmenu's prompt
  kconfig: delay gconf window initialization
  kconfig: expand by default the rootmenu's prompt
  kconfig: add a symbol string expansion helper
  kconfig: regen parser
  kconfig: implement the `mainmenu' directive
  kconfig: allow PACKAGE to be defined on the compiler's command-line
  kconfig: rephrase help texts/comments not to include the package name
  kconfig: allow build-time definition of the internal config prefix
  kconfig: rephrase help text not to mention the internal prefix
  kconfig: replace a `switch()' statement by a more flexible `if()' statement
