  New Revision: 65171

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=65171

  Log:
    configure.ac: add --disable-install-mjit-header
    
    and substitute INSTALL_MJIT_HEADER. This would be convenient as a workaround
    for user if we found a platform that can't compile Ruby after Ruby 2.6.0 release.
    
    common.mk: Install MJIT header only when INSTALL_MJIT_HEADER
    Makefile.in: ditto
    win32/Makefile.sub: ditto

  Modified files:
    trunk/Makefile.in
    trunk/common.mk
    trunk/configure.ac
    trunk/win32/Makefile.sub
