Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-81)
ab:~$ rpm -q libstdc++-devel
libstdc++-devel-2.96-113
ab:~$ cat test.cpp
#include <queue>
int main (int, char **)
{
queue<int> a;
queue<int> b;
a.swap(b);
}
ab:~$ g++ test.cpp -Wall
test.cpp: In function `int main (int, char **)':
test.cpp:7: no matching function for call to `queue<int, deque<int,
allocator<int>, 0> >::swap (queue<int, deque<int, allocator<int>, 0> >
&)'
So it seems g++ 2.96 doesn't have it. Or am I overlooking something?
