commit d3a2c66ebf4c8e00efd482601c11eec0c5e0a07f
Author: Maynard Johnson <maynardj@us.ibm.com>
Date:   Mon Jan 21 10:38:14 2013 -0600

    Fix compile warnings/errors with gcc 4.7.3
    
    On some distros, the struct poptOption in /usr/include/popt.h
    has the argInfo field defined as int, but on other distros,
    that field is defined as unsigned int.  In libopt++/popt_options.cpp,
    the option_base::option_base constructor passes an unsigned int
    popt_flags argument that's intended to be assigned to the
    argInfo field.  With gcc 4.7.1, the following warning(error) occurs
    on systems where the argInfo field is defined as an int:
    
    --------------
    popt_options.cpp: In constructor `popt::option_base::option_base
    (const char*, char, const char*, const char*, void*, unsigned int)':
    popt_options.cpp:255:51: error: narrowing conversion of `popt_flags'
    from `unsigned int' to `int' inside { } is ill-formed in C++11 [-Werror=narrowing]
    cc1plus: all warnings being treated as errors
    --------------
    
    The fix for this problem is to cast the popt_flags to the appropriate
    type using 'typeof(opt.argInfo)'.
    
    The second compile error (in pe_profiling/operf.cpp) is happening
    because the variable 'value' is assigned, but not used after that.
    This is dead code that should be removed.
