           Summary: Xorg-6.8.2: Wrong AMD64 optimization definition in
                    'host.def'
           Product: Beyond LinuxFromScratch
           Version: ~CVS
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: BOOK
        AssignedTo: blfs-book at linuxfromscratch.org
        ReportedBy: mail at chrschn.de
         QAContact: blfs-book at linuxfromscratch.org


When creating the 'host.def' file for the Xorg configuration the book's 
listing adds the following line to the file: 
 
/* #define DefaultGccAMD64Opt -O2 -fno-strength-reduce \ 
                              -fno-strict-aliasing */ 
 
Using this optimization definition has no effect an a AMD64 based system 
because the definition has a typo: a '2' is missing. The correct line would 
be: 
 
/* #define DefaultGcc2AMD64Opt -O2 -fno-strength-reduce \ 
                               -fno-strict-aliasing */
