The autoconf code in question completely disables AC_LINK_IFELSE. However, we know we can successfully do link tests when building natively. And, at least in libgcj's case, this knowledge is important because we use it to make libgcj more functional when built native. FYI I sent a patch to the autoconf list. Tom
