> Hm. The point of POSIX is to support cross platform development with a single standard. No, the point of POSIX is to specify a set of interfaces that software vendors should provide and target if their goal is to provide an UNIX variant or develop UNIX-compliant software. The key issue is that the main requirement is willingness on behalf of the software vendors to comply with the standard, and offer/target the standardized interface. If a software company is blatantly hostile regarding interoperability, and bases their business model on vendor lock-in strategies then it's quite obvious that those companies are particularly are not willing to play ball with others regarding interoperability. Yet, somehow you're presenting those companies, and the consequences of the actions taken by companies that are openly hostile regarding interoperability, as some sort of proof that a specific interoperability target suffers from technical problems.
