Solaris 10 doesn't follow POSIX in accepting a null pointer as the second argument to realpath(), so allocate a buffer for it.
FWIW, the NULL requirement is new in Issue 7. In Issue 6, the behavior is implementation-defined, and before then it was an error. Solaris 10 claims conformance to SUSv2 and its realpath fails with EINVAL. Solaris 11 says it conforms to Issue 6 but according to the man page its realpath already implements the Issue 7 requirement. I suspect the same problem will come up on other systems so checking the POSIX version might be better than testing for each OS. Martin
