Error description

  • Problem title
    Some AIX system header files have trailing space after
    backslash in continuation lines
    .
    Problem description
    In some AIX system header files, in some of the
    continuation
    lines, the backslash character \ has spaces between it
    and the end of line.  The xlc/xlC compilers ignore these
    spaces, and these lines are indeed joined with the one
    following, so there is no real harm in functionality.
    However, this feature is non-standard, and it elicits
    warnings with the -qinfo compilation option, and also
    from gcc/g++ with -wall.
    Please, remove these trailing spaces in continuation
    lines.
    The files found that have this problem are:
    j2_types.h and net_rules.h. This can be seen by using the
    grep command:
     -> grep -n '\\  *$' net_rules.h
    482:    (((hrule) &&
    514:    (((hrule) &&
    [] thompsor@ /tmp
     -> grep -n '\\  *$' j2_types.h
    551:    J2ERRAVOW(J2ERRALWAYS,\
    573:    J2ERRAVOW(J2ERRALWAYS,\
    596:    J2ERRAVOW(J2ERRALWAYS,\
    619:    J2ERRAVOW(J2ERRALWAYS,\
    
    The Fix is to delete the single space after the trailing
    backlash in the continuation lines.
