[PATCH] Fix _M_extract_int for grouped hexs and octs


Hi!

a bunch of espressos later ;-), here it is, fixed as Benjamin suggested. An
unexpected problem I had (i.e., one more coffee) is the following: with this
patch test01() was unexpectedly failing here:

  // const void
  iss.str("0xbffff74c.");
  iss.clear();
  err = goodbit;
  ng.get(iss.rdbuf(), 0, iss, err, v);
  VERIFY( &v != &cv );
  VERIFY( err == goodbit );

It turned out to be due to the terminal ".", which happens to be the
thousand_separator of "de_DE", now parsed for hexs too! Therefore I substituted
it with a comma.

I took also the occasion to remove 3 more static keywords lurking around.

Tested x86-linux, as usual.

Is it ok for head, and, after some more testing, 3.1 ??

Ciao, Paolo.

        * include/bits/locale_facets.tcc (num_get::_M_extract_int):
        Admit grouping for octals and hexadecimals too.
        * testsuite/22_locale/num_get_members_char.cc: Add test04.
        (test01): Tweak "." -> "," in void* test.
        * testsuite/22_locale/num_get_members_wchar_t.cc: Ditto.

        * testsuite/27_io/ios_manip_basefield.cc: Remove static keyword.
        * testsuite/27_io/ios_manip_fmtflags.cc: Remove two of them.
