    add flag to enable C99 mode with Solaris compilers
    
    Autoconf maintains a comprehenive list of ways to enforce C99 mode
    with various compilers.
    
    http://git.savannah.gnu.org/cgit/autoconf.git/tree/lib/autoconf/c.m4
    
    Since we regularly test with Sun/Solaris Studio, cherry pick the correct
    method to use with --enable-strict.

    increase feature level for pread/pwrite
    
    /usr/include/sys/feature_tests.h on Solaris says this about feature
    levels and C99:
    
       It is invalid to compile an XPG3, XPG4, XPG4v2, or XPG5 application
       using c99.  The same is true for POSIX.1-1990, POSIX.2-1992, POSIX.1b,
       and POSIX.1c applications. Likewise, it is invalid to compile an XPG6
       or a POSIX.1-2001 application with anything other than a c99 or later
       compiler.  Therefore, we force an error in both cases.
    
    ROMIO builds would fail with --enable-strict because _XOPEN_SOURCE=500
    was defined to expose pread/pwrite. Increasing the feature level to 600
    makes usage strictly compatible with C99.
