Hi Harald,

the Fortran standard requires an explicit procedure interface in certain
situations, such as when they have a BIND(C) attribute (F2018:15.4.2.2).
The attached patch adds a check for this.

Regtested on x86_64-pc-linux-gnu.  OK for mainline?

While this fixes the ICE, it misses

function f() bind(c)
   f = 42.
end

subroutine p
   bind(c) f     ! { dg-error "must be explicit" }
   x = f()
end

what do you mean by "it misses"?

Sorry, that was caused by confusion on my part (and it is better
to test an assumption of what the compiler actually does :-)

Patch is OK, also for backport.  Maybe you can also include the
test above, just to make sure.

Best regards
