E.g. "en_US" instead of "en". Add handling of LANG_SORBIAN. Fix typo for SUBLANG_CHINESE_SIMPLIFIED (China == CN, CH == Switzerland).

(create_events, g_io_win32_msg_write): Free message fetched with g_win32_error_message (). (g_io_win32_check): Indentation fixes. (g_io_win32_fd_read,g_io_win32_sock_read): Don't always return G_IO_STATUS_NORMAL. Do return G_IO_STATUS_EOF if we got 0 bytes, like on Unix. This helps making the test programs run successfully. * glib/gmain.c (g_poll): Return the code ifdeffed out with TEST_WITHOUT_THIS. Can't remember why it was ifdeffed out. Things seem to work as previously with the code in place. Especially spawn-test didn't work with the code ifdeffed out (Bug#61067). * glib/grand.c (g_rand_new): Don't try to use /dev/urandom unless on Unix. * glib/gspawn-win32-helper.c (WinMain): Remove Sleep(10000) accidentally left in. gthread: 2001-09-28 Tor Lillqvist <tml@iki.fi> * gthread-win32.c: Use an extra level of indirection for GMutex. It is now a pointer either to a pointer to a CRITICAL_SECTION struct, or to a mutex HANDLE. This is needed in case the user defines G_ERRORCHECK_MUTEXES. G_MUTEX_SIZE must correctly reflect the size of *GMutex, but this used to vary depending on whether we at run-time chose to use CRITICAL_SECTIONs or mutexes. (g_mutex_free_win32_cs_impl, g_cond_free_win32_impl): Call DeleteCriticalSection() when done with it. * gthread-impl.c (g_thread_init_with_errorcheck_mutexes): Call g_thread_impl_init() before accessing g_thread_functions_for_glib_use_default, as the g_thread_impl_init() function might modify it. po: 2001-09-28 Tor Lillqvist <tml@iki.fi> * POTFILES.in: Add iochannel.c and giowin32.c. * sv.po: Remove a bogus fuzziness indicator.
