+Subject: [PATCH] maint: fix operator precedence in mbrtowc test
+
+This is a fix for test breakage introduced by commit 45228d96; the
+equality expression must be parenthesized when negated with '!',
+otherwise we always get:
+
+  test-mbrtowc.c:49: assertion 'ret == (size_t)(-2)' failed
+
+* m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): Negate the entire expression.
+* m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): Likewise.
