When including a system header in a namespace followed by another system header
seems to prevent declarations being recognized in the headers or some such.
Even happens when the headers are both the same.
Example code:
#ifndef APP_H
#define APP_H
namespace win
{
#include <string>
}
#include <iostream>
#endif

The reason I thought I was a bug was because it works if the #include is before the namespace. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=35000 ^ permalink raw reply [flat|nested] 4+ messages in thread
