I suspect HOST_BITS_PER_INT will always be 32bit for all hosts GCC
will be supported but who knows. The point of the check is to find a
type which is at least 32bits enough to hold the wide character.
HOST_BITS_PER_* are defined in hwint.h:
#define HOST_BITS_PER_CHAR CHAR_BIT
#define HOST_BITS_PER_SHORT (CHAR_BIT * SIZEOF_SHORT)
#define HOST_BITS_PER_INT (CHAR_BIT * SIZEOF_INT)
#define HOST_BITS_PER_LONG (CHAR_BIT * SIZEOF_LONG)
#define HOST_BITS_PER_PTR (CHAR_BIT * SIZEOF_VOID_P)
Where SIZEOF_* are defined while doing a configure and CHAR_BIT is
defined in limits.h which is defined as a preprocessor constant.
Does that help you understand the code better?
ok, that makes things clearer now.
(I've actually never looked into hwint.h before. I should have.)
Thanks,
Harald
