Windows specific function for migrating from LibGlade to GtkBuilder
|

Glade had a gtk.glade.bindtextdomain() function to define the directory

where to look for translations (.mo-files). It is now replaced with call
|
|
to locale.bindtextdomain() which exposes the C librarys gettext

interface on systems that provide this interface.

As MS Standard Runtime C library have not such interface call to

Python's locale.bindtextdomain() is not supported on Windows systems.

"intl.dll" but private builds may use posix/ld-linker tradition like

"libintlX-X.dll" which in recent gettext version would be libintl-8.dll
