When configuring a gnulib testdir with a gcc 15 snapshot, this line
produces two warnings:
conftest.c:38:25: warning: comparison of constant '120' with boolean expression
is always false [-Wbool-compare]
38 | bool use_u8 = !u8"\xFF" == u8'x';
| ^~
conftest.c:38:25: warning: logical not is only applied to the left hand side of
comparison [-Wlogical-not-parentheses]
conftest.c:38:15: note: add parentheses around left hand side expression to
silence this warning
38 | bool use_u8 = !u8"\xFF" == u8'x';
| ^~~~~~~~~
| ( )
What is this line meant to test?
- Support for hex escapes in UTF-8 string literals?
- Comparison of bool values against int values?
