In cases like this, not without precautions. This only worked because Autoconf happens to know about GNU libc's __stub_* macros, and adds garbage to the test source file if the relevant one is defined, so that the compile phase fails. If the compile phase had succeeded, the link phase would have as well. The configure script would have declared that lchown() is available, and one would have ended up with a useless lchown() substitute. G.
