Merge changes from ruby_1_8 to reduce warnings and potentially improve

security.

* mkconfig.rb: hide build path from rbconfig.rb.

* util.c (ruby_strtod, dtoa): initialize more variables for error
  handling.

* io.c (rscheck), marshal.c (w_nbyte, w_bytes, w_unique),
  (path2class, path2module): constified.

* pack.c (pack_unpack), process.c (rb_syswait): suppress warnings.

* suppress warnings on cygwin, mingw and mswin.
