Don't call g_set_error() unless the GError pointer is non-NULL. This
2005-04-27 Tor Lillqvist <tml@novell.com> * glib/gconvert.c (open_converter, g_convert_with_iconv): Don't call g_set_error() unless the GError pointer is non-NULL. This avoids infinite recursion problems in certain rare situations on Windows, when g_locale_from_utf8() is called from _glib_get_locale_dir() after the change below. It's the _glib_gettext() calls to translate error messages that are parameters to g_set_error() that cause the recursion, not g_set_error() itself. * glib/gwin32.c (g_win32_locale_filename_from_utf8): New function. Converts a filename to the system codepage, and if a straight conversion isn't possible (because the filename contains characters not in the system codepage), try looking up the filename (which should refer to an existing file for this to succeed) with short (8.3) pathname components. * glib/gutils.c (_glib_get_locale_dir): No need to cache the result, this function is normally called only once. Return the path to the locale directory in system codepage, not UTF-8. The path is passed to bindtextdomain(), which doesn't use UTF-8 file names. Use g_win32_locale_filename_from_utf8(). (#301772) Don't do run-time lookup of message catalog directory on Cygwin. Cygwin is supposed to look and feel like Unix, and on Unix we use paths fixed at configure time.
