Old Solaris 8, once fully patched, was definately compliant with SUSv2 which is all of POSIX.1b-1993, POSIX.1c-1996
POSIX does not specify the behavior of grep when the input is not a text file, and a file that ends in a non-newline is not a text file. So Solaris grep and GNU grep can do what they like when the input ends in a non-newline; they don't have to agree with each other.
