Joseph S. Myers - fixinc v. glibc <values.h>

[Bruce Korb]

This diff is a consequence of this "fix":

  /*
   *  HPUX 10.x sys/param.h defines MAXINT which clashes with values.h
   */
  fix = {
    hackname  = hpux_maxint;
    files     = sys/param.h;
    files     = values.h;
    select    = "^#[ \t]*define[ \t]*MAXINT[ \t]";

    c_fix     = format;
    c_fix_arg = "#ifndef MAXINT\n%0\n#endif";
    c_fix_arg = "^#[ \t]*define[ \t]*MAXINT[ \t].*";

    test_text = '#define MAXINT 0x7FFFFFFF';
  };

I think from the comment, we can add:

  test =
  "-n \"`egrep '#[ \t]*define[ \t]+MAXINT[ \t]' sys/param.h`\"";

which will cause the fix to be applied only if the egrep
finds matching text in sys/param.h.  (The fixinclude working
directory is /usr/include.)

GCC's fixincludes makes the following changes to glibc 2.2's
<values.h>.  One of glibc and fixincludes is presumably buggy here;
which?
