Thanks Dietmar.

Seems the consensus is that it's not contrary to Standard, but it's agreed to
be confusing and undesirable by everyone except the gcc maintainers :-)

FWIW, the actual context in which I found the behaviour was this:

    if (whatever...)
    {
        stuff...
    }
    #ifdef FOO
    #pragma message ("QUICK AND DIRTY HACK!!!")
    else if (special case...)
    {
        other stuff...
    }
    #endif // FOO

I'll take a lot of persuading that this isn't a reasonable thing to want to do.
(Flagging the nasty, that is; purists who say you should never /do/ anything
you need to warn people about need not apply :-) )
