_t suffix is reserved by POSIX standard

[yoursunny]

According to libtool documentation and POSIX.1 standard section 2.2.2, some classes of identifier names are reserved for future extensions to the C language or the POSIX.1 environment. While using these names for your own purposes right now might not cause a problem, they do raise the possibility of conflict with future versions of the C or POSIX standards, so you should avoid these names.

One of them is names that end with _t suffix, reserved by POSIX.1 standard for additional type names.
ndn-lite contains declarations like:

ndn-lite/encode/interest.h

Lines 26 to 29 in 361ac33

	typedef struct interest_params {
	uint8_t value[NDN_INTEREST_PARAMS_BUFFER_SIZE];
	uint32_t size;
	} interest_params_t;

They should be changed to:

typedef struct interest_params {
  uint8_t value[NDN_INTEREST_PARAMS_BUFFER_SIZE];
  uint32_t size;
} interest_params;
