I am working for bcbboost, and I have begun making regression test, going from basics upwards. I have found (with my current configuration) therer *hundreds* of type_traits library tests that fail. I am trying to find a solution to those, but I cannot keep from wondering, was BCB6 also failing, and it is not important? Was it failing and nobody noticed? Am I failing to see the evident, and all my work process is poisoned form the beginning? To give an example, remove_const fails for the following cases: 2: volatile -> volatile 3: const volatile -> volatile 7: *volatile -> *volatile 8: *const volatile -> *volatile 13: volatile[2] -> volatile[2] As I have seen on other threads, there might be an issue with the order of quialifications, so maybe the soltunio is to redefine the test macros, but I hope someone will give me some idea to continue with minimum effort. TIA, bes regards, Zara
