Could you please explain the point of the patch?
Is it to simplify debugging, or improve performance, or what?
I don't see the advantage over the current approach.
> +#define DEFGCPRO1 void *__dummy ATTRIBUTE_UNUSED = &__dummy
This would be cleaner if DEFGCPRO1 etc were either empty,
or expanded to something that ended in ";". Then the caller
can just do "DEFGCPRO1" (without the semicolon) and there's
no need for dummy declarations.
> +#define IF_GCPRO(code) do { } while (0)

IF_GCPRO should act more like a function, i.e., its argument
should be an expression and it should expand to an expression.
This is more consistent with how typical macro-like functions work.
The above should be:
#define IF_GCPRO(expr) ((void) 0)
...
#define IF_GCPRO(expr) (expr, (void) 0)
and calls like this:
IF_GCPRO (gcpro3.nvars = nargs; gcpro4.nvars = nargs);
should be replaced by:
IF_GCPRO ((gcpro3.nvars = nargs, gcpro4.nvars = nargs));

This I do not understand. Macros without the semicolons make cc-mode
have to work much, much harder to determine the current level of
indentation. I also find it offputting to see something that looks like
a statement that does not terminate with a semicolon.

+1. Actually cc-mode just fails to get indentation level right after such a macro. If on the other hand we would allow declarations after statements, a lone semicolon would not matter.

True. But surely there is a better way to solve this problem.
As things stand, the patch proposes a macro that
declares a dummy variable that's unused, primarily in order
to avoid declaring some other variable that's unused. Why
is this a win? After all, we have an unused variable either way.

I don't think it's terribly important to do that.
Unused variables are largely harmless. Getting rid of unused structure
fields is OK, so feel free to commit this part of the patch.
I'm not completely averse to replacing those "struct gcpro gcpro1,
gcpro2, ..." with some kind of macro (tho I'd make it take an argument,
much like EXFUN), but then I'd like to find some way to make them expand
to something more empty than "*__dummy ATTRIBUTE_UNUSED = &__dummy".
This said, I don't like the suggestion to include the semi-colon in the
DEFGCPRO macros, so I'm not sure how else to do it, without bumping into
the "declarations after statements".
