when compile following file[1] with option `-Wall', it will give a
warning[2]. g++-4.0 do not has this problem. I don't think this
warning is proper.
[1]
// begin array2.cpp
#include <tr1/array>
int main() {
std::tr1::array<int, 2> foo = {0, 1};
return foo[1];
}
// end
[2]
array2.cpp: In function 'int main()':
array2.cpp:4: warning: missing braces around initializer for 'int [2]'

How-To-Repeat:
array.ii.bz2 is in attachment, uncompress it. then use
'g++-4.1 -Wall -c array.ii' to reproduce this bug.
------- Comment #1 from lidaobing at gmail dot com 2006-04-04 05:41 -------
Fix:
work around, the following code will not generate warning with
'-Wall', but it looks strange.
// begin
#include <tr1/array>
int main() {
std::tr1::array<int, 2> foo = {{0, 1}};
return foo[1];
}
//end
