[Bug c++/41020] New: Can't declare an extern "C" friend.

[Bug c++/41020] New: Can't declare an extern "C" friend.

[davek at gcc dot gnu dot org]

Attempting to declare a previously-declared extern "C" function as a friend
within a class definition fails with an error that the friend declaration
ambiguates the original extern "C" declaration.  It appears that the friend
declaration is taken as an overload with "C++" linkage, since G++ then
complains that the class members are private within the context of the extern
"C" function definition.

$ cat friend.cxx

extern "C"
{
  int fork (void);
};

class frok
{
  int this_errno;
  friend int fork (void);
};

extern "C" int
fork (void)
{
  frok grouped;
  return grouped.this_errno;
}

$ g++-4 -c friend.cxx -o friend.o
friend.cxx:10:24: error: new declaration 'int fork()'
friend.cxx:4:7: error: ambiguates old declaration 'int fork()'
friend.cxx: In function 'int fork()':
friend.cxx:9:7: error: 'int frok::this_errno' is private
friend.cxx:17:18: error: within this context

$

  According to, for example, "C++ in a nutshell"
(http://books.google.co.uk/books?id=91JTA9B_m44C&pg=PA170&lpg=PA170&dq=friend+%22storage+class%22&source=bl&ots=HrN4X1Y5wu&sig=N9rnB8r_YnxbH2hiWGqtbAWbWyk&hl=en&ei=oDt_SqmvGJKNjAe9k93wAQ&sa=X&oi=book_result&ct=result&resnum=5#v=onepage&q=friend%20%22storage%20class%22&f=false),
a function in a friend declaration should "retain its original linkage" when it
has already been declared.  That is referring to the case of applying a storage
class specifier (static) to the prior declaration that isn't syntactically
valid within a friend declaration, but it seems like it should apply here too;
the linkage should still be retained, even though I'm not changing the
storage-class specifier.

  There may be some reason why this isn't valid C++, but I think it's probably
a weakness in the parsing of friend declarations.

  Yuck, that got horribly wrapped.  Here it is again, hopefully formatted a

Apart from the semi-colon after the extern "C" block the code is valid and this
is a recent regression on trunk.

I am fairly sure that a semi-colon after a block statement like that is
unnecessary, but not actually invalid.  It certainly makes no difference to the
testcase whether it is present or absent.

It's irrelevant to this bug and is just me being more pedantic than -pedantic,
however ... even with -pedantic GCC has always accepted stray semi-colons at
namespace scope, but it's not valid.

At function scope a lone ';' is a valid expression-statement, but
expression-statements are not allowed at namespace scope, only declarations
are, and ';' is not a valid declaration.

  Well you learn something new every day!  Never realised that was a gnu
extension, but it sure is, comeau online choked on my testcase:

"ComeauTest.c", line 5: error: extra ";" ignored,
        In C: A function definition does not end with a semicolon
        In C++: A non-member function definition, extern "C" block,
                or namespace does not end with a semicolon
  };
   ^
  Anyway.  Consider the testcase amended.  :-)

$ cat friend.cxx

extern "C"
{
  int fork (void);
}

class frok
{
  int this_errno;
  friend int fork (void);
};

extern "C" int
fork (void)
{
  frok grouped;
  return grouped.this_errno;
}

$ g++-4 -c friend.cxx -o friend.o

This is related to builtins too because either using -fno-builtin or using
fork1 allows this program to work.
