- 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.
