    32 # This makefile uses the default settings for where to find compilers and

    44 #  ALT_EXPORT_PATH            Directory to export hotspot build to
    45 #  ALT_JDK_IMPORT_PATH        Current JDK build (only for create_jdk rules)
    46 #  ALT_BUILD_WIN_SA           Building SA on Windows is disabled by default.
    47 #                             Set ALT_BUILD_WIN_SA=1 to enable building SA on
