           Summary: Triple ADT sometimes extracts wrong vendor and os
           Product: new-bugs
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
        AssignedTo: unassignedbugs at nondot.org

Here are some example triples printed by various gcc versions on my linux
machine:

1) System gcc: x86_64-linux-gnu
2) 32 bit system gcc: i486-linux-gnu
3) ACT supplied gcc: x86_64-pc-linux-gnu
4) 32 bit ACT supplied gcc: i686-pc-linux-gnu
5) self-built gcc-4.5: x86_64-unknown-linux-gnu
6) 32 bit self-built gcc-4.5: i686-pc-linux-gnu

If the Triple class is instantiated with 1) or 2) then
getVendor and getOS return their 'unknown' value.
