Hi Jaroslav
on cygwin double and long double are not equal.
sizeof(int) == 4
sizeof(long) == 4
sizeof(long long) == 8
sizeof(long long int) == 8
sizeof(unsigned long long int) == 8
sizeof(double) == 8
sizeof(long double) == 12
sizeof(int8_t) == 1
sizeof(int16_t) == 2
sizeof(int32_t) == 4
sizeof(int64_t) == 8
sizeof(uint8_t) == 1
sizeof(uint16_t) == 2
sizeof(uint32_t) == 4
sizeof(uint64_t) == 8
