# NOTE: the current test bench may include K&R style C, C89 style C, C99 - and
|
|
# even things from later standards. Technically C99 removed certain C89
|
|
# constructs - However, so far GCC would still compile them and issue a
|
|
# warning (instead of an error). Now, GCC 14 will be more strict about this,
|
|
# and by default make those things an error instead. We use -std=gnu17 here
|
|
# so we can still build the references with a modern compiler, and don't
|
|
# have to deal with special-casing individual tests that use constructs
|
|
# from those old standards. Should this become a problem in the future, we
|
|
# will have to change that, and create said special cases here.
