I do not think the CRYPTO_TDEBUG macro is really useful, it pre-dates 3.x releases and basically switches off multithreading support. But it is not tested and I would be very much surprised if the OpenSSL code builds with it being defined. It is not clear to me, why are you seeing any compilation errors. Unless you try to typedef CRYPTO_ONCE or the other typedefs we have in the crypto.h header yourself. Could you please share a snippet of your code where you see the compilation error?
