src/olsr_types.h: fix boolean type check with C23 - #139
Merged
Conversation
GCC 15 defaults to GNU C23. In C23, bool, true and false are keywords, and <stdbool.h> no longer defines __bool_true_false_are_defined. Therefore the existing preprocessor check incorrectly rejects a valid C23 environment. Keep the check for older C standards, where these identifiers must be provided as macros by <stdbool.h> or by the GNU C fallback. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
