The libc5 version of this program will use the name of a library given on the command line as-is when it contains a /; otherwise it searches for the library in the standard locations. To run it on a shared library in the current directory, prefix the name with "./".
ldd does not work with some extremely old a.out programs which were built before ldd support was added to the compiler releases. If you use ldd on one of these programs, the program will attempt to run with argc = 0 and the results will be unpredictable.
