           Summary: incorrect dup() behavior
           Product: Wine
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-msvcrt
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: pclouds at gmail.com


I consider it incorrect although I may be wrong about this. The following
program returns 1 on Windows but 3 on Wine:

#include <stdio.h>
int main(int argc,char **argv) {
        close(1);
        fprintf(stderr,"%d\n",dup(2));
        return 0;
}

An exception was made in msvcrt_free_fd() to avoid using file handles < 3 for
dup(). Is it really necessary?
