That would be up to the compiler vendor. It is neither required nor forbidden by the standard. Prior to f90, the standard had *NO* requirements for compiler diagnostics. Starting with f90, there are some requirements, but this would not fall under them.
Actually, I'd expect most current compilers to not even have an option to accept this one. For those that do accept it... hmm... all cases aren't necessarily detectable at compile time (since formats can be constructed at run-time these days). Switches to control run-time detection of things exist, but are not as common as compile-time options. I'm not sure what to expect. Since this particular feature predates run-time format construction, it seems quite plausible to me that compilers that do allow it today might allow it only in format statements (where compile-time detection would be simple).
But this isn't something I've tested, so most of the above is just guesses, and not ones I would stand behind very much - except for the bits about the requirements of the standard. This feature isn't something you see very much. I've managed to go quite a few years between "sightings". Some others over at comp.lang.fortran would probably know this one better than I do. I had managed to even forget about this feature for a long time, though I got reminded of it a few years ago.
Hmm. You've lost me there. Did there used to be an issue with that? My f66 proficiency is a little rusty (and I'm not feeling like dragging out either the f66 standard or the f77 Appendix on compatibility right at the moment). I recall some special limitations on END lines (mostly relating to continuation), but I don't off-hand recall a restriction against and END line having a label. There certainly is no restriction against that now; I'm pretty sure I would have recalled any such thing in f77 or later.

I am an engineer.* I use Fortran, mostly F77 dialect. I also use other computing tools, including Excel. QuattroPro was MUCH better than Excel for years for any...
