           Summary: Hardlinks not work with #import
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: objc
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: wo701 at yahoo dot com

After submit bug for symlinks not work with #import, I looked at hardlinks
and noticed they fail too.  They work with 2.95.

Testcase:

create file1.h:

#warning "File imported"

create file2.h, hardlink to file1.h:

ln file2.h file1.h

compile main.m:

#import "file1.h"
#import "file2.h"

int main() {exit(0);}

2.95 prints out "File imported" once, correct; new gcc prints out "File
imported" twice, wrong.
