blob源码中configure.in的问题

AC_DEFINE(ASSABET) //AC_DEFINE (variable [, value [, description]])
//定义C预处理器变量variable。如果给出了value，就把variable设置成那个值（不加任何改变），否则的
//话就设置为1。value不应该含有新行，同时如果你没有使用AC_CONFIG_HEADER，它就不应该含有任何`#'
//字符，这是因为make将删除它们。为了使用shell变量（你需要使用该变量定义一个包含了 m4引用字
//符`['或者`]'的值），就使用AC_DEFINE_UNQUOTED。只有在你使用AC_CONFIG_HEADER的时候，description才有用。
//在这种情况下，description被作为注释放置到生成的`config.h.in'的宏定义之前；不必在`acconfig.h'中提及该
//宏。下面的例子把 C预处理器变量EQUATION的值定义成常量字符串`"$a > $b"'：
//AC_DEFINE(EQUATION, "$a > $b")
AC_DEFINE(EQUATION, "$a > $b")
BLOB_PLATFORM_OBJ="assabet.o"
AC_MSG_WARN([Please check assabet memory config in arch/assabet.h]) //告知configure的使用者可能出现的问题。本宏在标准错误输出中打印消
//息；configure继续向后运行，所以调用AC_MSG_WARN的宏应该为它们所警告
//的情况提供一个缺省的（备份）行为。 problem-description应该是类似于
//`ln -s seems to make hard links'的东西。

问题是assabet，neponset, brutus, creditlart, h3600等各代表什么？？？
