Subject: * rclex.c: (cpp_line): Add code_page pragma support. * windres.c:
 (usage, long_options, main): Add new option --codepage or -c. * winduni.c:
 (wind_default_codepage, wind_current_codepage): New.   (unicode_from_ascii,
 ascii_from_unicode): Use wind_current_codepage as codepage parameter.  
 (unicode_print): Print 4 characters for hexadecimal values in unicode
 strings. * winduni.h:  (wind_default_codepage, wind_current_codepage):
 Export. * doc/binutils.texi: Document new option. * NEWS: Mention new
 feature.
