Between 20060508 and 20060530 gcc 4.2 changed to now longer allow the following
code. This error seems bogus to me.
(sid)3733:tbm@test: ~] cat test.cc
extern "C" void foo(register int *my_perl);
(sid)3734:tbm@test: ~] c++ -c test.cc
test.cc:1: error: invalid use of 'register' in linkage specification
zsh: exit 1 c++ -c test.cc
(sid)3735:tbm@test: ~]

I want to say the patch for PR 26068 caused this.

It's certainly a questionable use of 'register'. What is the expected effect
of this parameter declaration from perls point of view?

------- Comment #3 from tbm at cyrius dot com 2006-06-04 10:24 -------
I don't know why Perl uses it, I simply noticed that lots of packages in Debian
now fail to build because its part of a Perl header... they do this:
extern "C" SV* Perl_Gsv_placeholder_ptr(register PerlInterpreter *my_perl
__attribute__((unused)));
In an IRC discussion whether this is valid, the following comments were made:
18:11 < Womble2> "a linkage-specification directly containing a single
declaration shall not specify a storage class" (7.5/8)
18:12 < Womble2> but I think it really means at the top-level of the
declaration
18:12 < pinskia> Womble2: I think that means extern "C" static int t; is
invalid
18:12 < Womble2> yes the example it gives has a function declared a static
18:13 < pinskia> but register allows to the argument and not to the declaration
18:13 < pinskia> s/allows/applies/
18:14 < Womble2> indeed, though the statement could be (rather perversely) read
as disallow specification of a storage class anywhere in the declaration, as
the person who made the change may have done
[Womble2 = Ben Hutchings, pinskia = Andrew Pinski]
Do you disagree with that interpretation?

I agree that the code is valid from a standards perspective. Just not very
clever ;)

OK, I'll let the Perl people know. It would be nice though to revert this
error before 4.1.2/4.2.0 come out.
