Wrapper

The wrapper allows wrapping Fortran statements in C declations

$ fsource wrap [--fixed-form] FILENAME [FILENAME ...]

The result is a C header file.

Exact type maps

The following maps are exact:

Fortran	iso_c_binding KIND	sizeof	C type	numpy dtype
LOGICAL	c_bool	1	_Bool	bool_
CHARACTER	c_char	1	char	char
INTEGER	c_int		int	intc
INTEGER	c_short		short	short
INTEGER	c_long		long	int_
INTEGER	c_long_long		long long	longlong
INTEGER	c_signed_char	1	signed char	byte
INTEGER	c_size_t		ssize_t	intp
INTEGER	c_int8_t	1	int8_t	int8
INTEGER	c_int16_t	2	int16_t	int16
INTEGER	c_int32_t	4	int32_t	int32
INTEGER	c_int64_t	8	int64_t	int64
INTEGER	c_intptr_t		intptr_t	intp
INTEGER	c_ptrdiff_t		ptrdiff_t	intp
REAL	c_float	4	float	float32
REAL	c_double	8	double	float64
REAL	c_long_double		long double	longdouble
COMPLEX	c_float_complex	8	float _Complex	complex64
COMPLEX	c_double_complex	16	double _Complex	complex128
COMPLEX	c_long_double_complex		long double _Complex	clongdouble

The sizeof column indicates, e.g., that INTEGER*4 is equivalent to int32_t, which is true on major (all?) platforms.
