Here's the relevant bit of tags.h. From config.status it doesn't look
as if SCM_DEBUG_TYPING_STRICTNESS is defined. This is confirmed by
compiling using make clean; make
CFLAGS=-DSCM_DEBUG_TYPING_STRICTNESS=1 I get a different set of
totals at the end of ./check-guile --debug
passes: 2077
failures: 7
unexpected passes: 0
expected failures: 17
unresolved test cases: 2
untested test cases: 0
unsupported test cases: 9
errors: 30
(There were on unresolved test cases when compiled without defining
SCM_DEBUG_TYPING_STRICTNESS)
#if (SCM_DEBUG_TYPING_STRICTNESS == 2)
typedef union { struct { scm_t_bits n; } n; } SCM;
static SCM scm_pack(scm_t_bits b) { SCM s; s.n.n = b; return s; }
# define SCM_UNPACK(x) ((x).n.n)
# define SCM_PACK(x) (scm_pack ((scm_t_bits) (x)))
#elif (SCM_DEBUG_TYPING_STRICTNESS == 1)
/* This is the default, which provides an intermediate level of compile time
* type checking while still resulting in very efficient code.
*/
typedef struct scm_unused_struct * SCM;
# define SCM_UNPACK(x) ((scm_t_bits) (x))
# define SCM_PACK(x) ((SCM) (x))
#else
/* This should be used as a fall back solution for machines on which casting
* to a pointer may lead to loss of bit information, e. g. in the three least
* significant bits.
*/
typedef scm_t_bits SCM;
# define SCM_UNPACK(x) (x)
# define SCM_PACK(x) ((scm_t_bits) (x))
#endif
Running gcc -E tags.h shows that
typedef scm_t_bits SCM;
is the line included.
Thanks for your help,
David
