[David W. Schuler]

I've done some work in debugging the following errors under AIX 4.1.5:

>FAIL: g77.f-torture/execute/u77-test.f execution,  -O0 
>FAIL: g77.f-torture/execute/u77-test.f execution,  -O1 
>FAIL: g77.f-torture/execute/u77-test.f execution,  -O2 
>FAIL: g77.f-torture/execute/u77-test.f execution,  -O2 -fomit-frame-pointer -finline-functions 
>FAIL: g77.f-torture/execute/u77-test.f execution,  -O2 -fomit-frame-pointer -finline-functions -funroll-loops 
>FAIL: g77.f-torture/execute/u77-test.f execution,  -O2 -fomit-frame-pointer -finline-functions -funroll-all-loops 
>FAIL: g77.f-torture/execute/u77-test.f execution,  -Os 

First, it's probably very important to explain my environment:

    Home directory is in AFS, with a dual-client AFS/DFS system
    EGCS code is located in an area that is NFS-mounted to yet another box

That said, when I run the u77-test.f code, it aborts at line 225 with the
following output:

    ...
     Current directory is "/usr/local/x86srvr1/WORKSPACE5/schuld/EGCS/egcs-19990428-aix41/gcc/tmp"
     Creating file "foo" for testing...
     with stat array  -2147483629 2900650 33206 1 2359 3 2913149 2 925407554
      925407554 925407554 4096 8
     *** FSTAT uid, gid or nlink is wrong

The code in this area is:

      if (statb(5).ne.getuid () .or. statb(6).ne.getgid() .or. statb(4)
     +     .ne. 1) then
        write (6,*) '*** FSTAT uid, gid or nlink is wrong'
        call abort
      end if

I did some further investigation, and found the statb(6) result the stat()
call (executed a few lines prior to the above code) is returning a gid value
of "1597", but get getgid() call returns "3".  The "1597" is the gid value in
the /etc/passwd file, and "3" is the entry for "sys".  I notice that all of my
files are created with a gid of "3".  I believe this to be an "AFS-ism", and
not an error in the g77 code itself.

Perhaps someone with more knowledge of AFS (and DFS) could think about how
this code could/should be restructured to take AFS and/or DFS into account
when running this test.  Is there anything unique that should be added to
the testcases specifically for AFS or DFS enabled systems???
