Note that a proposal for named arguments was recently presented to the C++
standards committee [1], and they did not seem receptive to it [2].
The proposal was for a different syntax (name : value), but the objections were
not related to the syntax.

Hello,
Now that the C++11 standard has been officially voted in, there is nothing
"experimental" about it any more.
Would it be possible to remove the warning about GCC's C++11 support
being experimental from http://gcc.gnu.org/projects/cxx0x.html, and
to modify the __GXX_EXPERIMENTAL_CXX0X__ m
Hi,
I'm wondering, are there are other new C++11 features planned
for GCC 4.7 besides "Extended friend declarations" and "Explicit
virtual overrides" (which are marked as already implemented at
http://gcc.gnu.org/projects/cxx0x.html)?
Thanks,
Nate
Hello,
So many times I write code like this:
SomeType function()
{
SomeType result;
// do something with result
return result;
}
except I often forget the "return result" statement.
Why does gcc not give an error about this?
If I compile with "-Wall", it will give a WARNING say

Hello,
The attached minimal code (test.cpp) causes g++ to
segfault. It uses the C++0x features variadic templates and initializer
lists.
The command used to compile it is:
g++ -std=c++0x test.cpp
The output is:
test.cpp: In function ‘void f(const Args& ...) [with Args = ]’:
test.cpp:21: i
Hello,
I've just build the gcc trunk and tried to compile some code that compiled fine
with gcc 4.5.
It gave an internal compiler error.
I've reduced it to the following minimal test case:
#include

int main()
{
std::map m;
std::pair p;
m.insert(p);
return 0;
}

Hello,
For the following code:

{

}
gcc 4.6 trunk gives the following errors (with the --std=c++0x option):

Hi,
I'm just wondering, is there any chance of fixing PR 50025 [1] soon?
It concerns uniform initialization of a class member of reference
type.
I have been using GCC to do C++11 development for a while now, and
this one bug has been a bit of an eyesore IMO, that has been
keeping the "uniform" ou

This warning is new in GCC 4.8, and I have been seeing a ton of them
not just in boos
