I use my own typedefs for portability.
I simply redefine the typedefs to get the required length and
characteristics.
For example SINT32 is a Signed 32 bit Integer anywhere I go and
P - Positive, U - Unsigned
They are nice and intuitive and not very ugly :-)
My typedefs for the VAX are:
typedef	long		PINT32;
typedef	long		SINT32;
typedef	unsigned long	UINT32;
typedef	long		BIT32;

typedef	short		PINT16;
typedef	short		SINT16;
typedef	unsigned short	UINT16;
typedef	short		BIT16;

typedef	char		PINT8;
typedef	char		SINT8;
typedef	unsigned char	UINT8;
typedef	char		BIT8;
