============================================================
Plan 0.25.0

  - Fix USE_SSP support for clang (-mllvm -stack-protector-buffer-size=1)
  - @sysconfdir@/mkc.conf
  - LDFLAGS vs. LDFLAGS in link.me (global paths before project's)
  - .RECURSIVE/.MAKE: -> mkc_imp.sub{dir,prj}.mk
  - "mkcmake all" ignores MKC_REQD
  - BMAKE_REQD - minimum required bmake version
  - virtual subprj - check for subprj/Makefile, not subprj
  - Reimplement linkme.mk. It is not flexible enough.
  - USE_RPATH
  - OBJCOPTS_<proj>
  - Regression tests:
    * optional .f tests
    * optional .p tests
    * optional .m tests
    * optional(!) glib2 tests

============================================================
Plan 1)

  - Support for MKDEBUG like in NetBSD mk files
  - .lua.luac:
  - disable caching for "negative" results
    for MKC_REQUIRE_xxx features.
  - Implement mkc_imp.libtool.mk to build
    the shared libraries using GNU libtool(1).
  - MKSTRIP, STRIP, mkc_install: use STRIP, not STRIPPROG

  Slides for:
    - Slide "extensibility" about Lua module.
    - code specific to GNU ld(1) (.def?)

============================================================
Plan 2)

  - ./configure written in shell?
  - EXPORT_DYNAMIC_SYMBOLS - add the specified symbols to
    dynamic symbol table (GNU ld)
  - EXPORT_SYMBOLS_REGEXP

  - recheck documentation for Makefile.rec
  - Syllable, Haiku, OpenServer/UnixWare and HURD
  - lcc and tcc compilers
  - epm -> rpm, SVR4 pkg etc.
  - mkc_imp.filelist.mk
    - FL_NOPREFIX
    - FL_PERSUBPRJ
  - IRIX: "endianess" and EXPORT_SYMBOLS

============================================================
Plan 3)

  = sample for home-made .mk file (Ocaml? Pike?)
  = marker for user's custom tests that
    run generated executables, i.e. not ready
    for cross-compilation

  = symlinks to executables and libraries in ${OBJDIR}/{bin,lib}

  = support for gettext

  = xxxDIR variable for /var

  = mkclint?

  = Command line may be limited in size.
    Save defines to config.h and set HAVE_CONFIG_H to 1
    for compiling.

  = MKC_NEED_FUNCLIBS - the same as MKC_SOURCE_FUNCLIBS but
    implementation is taken from mk-c.
    Ex: MKC_NEED_FUNCLIBS += strlcat strlcpy getline

  = MKC_CUSTOM_premk, MKC_CUSTOM_postmk

  = Online tutorial

  = shared libraries support for AIX, UnixWare, Hurd, Haiku.
  = shared libraries support for nwcc and other compilers.

  = Comparison with quagmire, kBuild, CMake, scons, waf, framewerk, pmk,
    MagicMakefiles, bjam, pymake etc.

  = Often compilers need special options to compile pthread code.
    Support for MKPTHREAD=yes|no is needed.

  = implement MANBZ2?

  = man page for mkc_check_compiler

============================================================
Plan 4)

  = EXPORT_SYMBOLS for HP-UX, AIX, SCO etc.

  = Single cache file as an automatically loaded (if exists)
    bmake makefile.

  = Targets bin_rpm, bin_epm
  = Targets src_tar, src_targz, src_tarbz2

  = mkc.subdir.mk:
    - continue bulding even if some subprojects failed

  = mkc.subdir.mk, mkc.subprj.mk: reimplement ${dir}.${MACHINE}

  = MKC_CHECK_CUSTOM:
    - MKC_CUSTOM_FN=xxx.f
    - MKC_CUSTOM_FN=xxx.objc

  = user-defined postinstall and preinstall?

  = Implement mkc.qt.mk

  = Implement mkc.doxygen.mk?

============================================================
Plan 5)

  = mkc.configure.mk functionality but for bourne shell, e.g.

    Upstream creates ./configure shell script:
      MKC_CONFIG_MK=mkc_config.mk
      MKC_CONFIG_H=mkc_config.h

      MKC_CHECK_HEADERS='
        header1.h
        header2.h
        header3.h'
      MKC_CHECK_FUNCLIBS='
        func1:lib1
        func2
        func3:lib3'
      #<...>
      . mkc_configure
      mkc_run # generating mkc_config.h and mkc_config.mk

    User runs
      ./configure ...
      <any>make all

  = MKC_CHECK_DECL_TYPE (define, function|variable)

  = MKC_DEFINE_01 - -DHAVE_XXX=0 or -DHAVE_XXX=1

============================================================
Plan 6)
  = MKC_BUILTINS (from autoconf):
      broken_free_NULL,
      exit_ret_int,
      isinf, isnan, malloc_0, putenv_xxx, realloc, signal,
      snprintf, sprintf, sscanf, strerror_r, strnlen,
      sysconf, unlink, unsetenv, va_copy, va_list,
      signed_shr, int_div, chown_minus_1,...
      (autoconf.info/Particular Function Checks)

      AC_FUNC_ALLOCA
  = autoconf (Portability of headers)
  = autoconf (Particular Header Checks)
