Howdy, Bug #1006 reports that ln -s /tmp/foo . does not work correctly. In fact, it appears that any instantiation of ln -s FILE... DIRECTORY does not work. The following patch adds support for this form, which then fixes the particular instance noted in the bug report. In the process, I needed the basename function. This appears in the string.h provided by glibc, but not uC-libc. So I wrote my own to go in utility.c, called get_last_path_component. I also modified the basename utility to use this function. At some point it might be desirous to use the basename from the library if it exists, and otherwise compile our own. But I don't know how to do this. Matt
