* ruby.h, lib/mkmf.rb (create_header): clear command line options for

macros moved to extconf.h.

* ext/extmk.rb (extract_makefile, extmk): made RUBY_EXTCONF_H and
  EXTSTATIC permanent.

* ext/{dbm,digest/*,socket,zlib}/extconf.rb: used $defs and $INCFLAGS.

* {bcc32,win32,wince}/Makefile.sub (COMPILE_C, COMPILE_CXX): added
  $(INCFLAGS).
