Re: executable-command-find-posix-p still bogus

[Richard Stallman]

    executable-command-find-posix-p is still bogus, and used (in
    filecache.el).  Thus I assume Filecache is currently broken on Solaris
    and other Unix systems.

Can you fix it?

    To repeat what I said before: it's not at all clear what it's trying
    to do or why, and it returns nil on non-GNU POSIX systems since it
    explicitly tests for something _non-POSIX_.

I had to think about that sentence several times before I understood
what you meant to say.

The goal appears to be to determine the right way to pass the wildcard
argument.  Can you write code that correctly decides which way to pass
that argument?  Perhaps just by testing system types is the best way.
That is not elegant, but if the number of systems that are exceptions
is small, it will work and won't actually need much maintenance.
