* common/w32-misc.c: New. * common/t-w32-cmdline.c: New. * common/init.c: Include w32help.h. (prepare_w32_commandline): New. (_init_common_subsystems) [W32]: Call prepare_w32_commandline. * common/Makefile.am (common_sources) [W32]: Add w32-misc.c (module_tests): Add t-w32-cmdline (t_w32_cmdline_LDADD): New. -- The rules for the command line parser are not cleary specified - if at all. See the comment in t-w32-cmdline.c. We can't use the mingw version because that would require to change all argv handling to be wchar_t and that only for Windows. That would be too ugly. Parsing the command line into argv by us is much easier and we can do that only if needed - i.e. if globing is required (we are prepared for this) or a non-ASCII character has been encountered. This way we keep things stable and only fix the currently not working Unicode problem. GnuPG-bug-id: 4398
