Update.
2001-05-21 Bruno Haible <haible@clisp.cons.org> * wcsmbs/mbrtowc.c (mbrtowc): Remove local variable 'flush', always use 0 instead, and rely on the converter to do the flush. * wcsmbs/tst-mbrtowc.c (utf8_test_1): New function, taken from utf8_test. (utf8_test_2, utf8_test_3): New function. (utf8_test): Call utf8_test_1, utf8_test_2, utf8_test_3.
