* configure.ac: Remove checks for stdint.h; we require C99 so it must be
there; and in any case for our purposes we use gnulib, so it will be
there. No need to check for inttypes.h. No need to check for what
type maps to e.g. uint32_t either.
* libguile/deprecated.h (SCM_HAVE_T_INT64, SCM_HAVE_T_UINT64): Deprecate
these, as they are always 1.
(SCM_HAVE_ARRAYS): Likewise deprecate; it's always 1.
* libguile/gen-scmconfig.c: Always include stdint.h and stddef.h, and
make it so that scmconfig.h also includes these. Use C99 types.
* libguile/gen-scmconfig.h.in: Remove configure-substed vars that are no
longer defined.
* configure.ac: Add a check for struct GC_stack_base.reg_base, which is
a proxy for checking for the only aspect of ia64 that we care about.
* libguile/gen-scmconfig.c:
* libguile/gen-scmconfig.h.in: Arrange to define
SCM_HAVE_AUXILIARY_STACK.
* configure.ac: Check for the iconveh values here, instead of relying on
gen-scmconfig to know them. That doesn't work in general because
gen-scmconfig runs on the build machine, not the target machine.
* libguile/Makefile.am (gen-scmconfig.$(OBJEXT)): Revert rule to the
revision before 533d8212.
* libguile/gen-scmconfig.h.in (SCM_I_GSC_ICONVEH_ERROR):
(SCM_I_GSC_ICONVEH_QUESTION_MARK):
(SCM_I_GSC_ICONVEH_ESCAPE_SEQUENCE):
* libguile/gen-scmconfig.c: Use configure-time substitutions to set
SCM_ICONVEH_ERROR_HANDLER et al.
* configure.ac: Check for `intptr_t' and `uintptr_t'. Substitute
`SCM_I_GSC_T_INTPTR' and `SCM_I_GSC_T_UINPTR'.
* libguile/__scm.h (SCM_T_UINTPTR_MAX, SCM_T_INTPTR_MIN,
SCM_T_INTPTR_MAX): New macros.
* libguile/_scm.h (SIZEOF_SCM_T_BITS): New macro.
* libguile/gen-scmconfig.c (main): Produce typedefs for `scm_t_intptr'
and `scm_t_uintptr'.
* libguile/gen-scmconfig.h.in (SCM_I_GSC_T_INTPTR, SCM_I_GSC_T_UINPTR):
New macros.
* libguile/tags.h: Don't check for `HAVE_INTTYPES_H' and
`HAVE_STDINT_H'; don't include <inttypes.h> nor <stdint.h>.
(scm_t_signed_bits, scm_t_bits): Define unconditionally as aliases for
`scm_t_intptr' and `scm_t_uintptr', respectively.
(SCM_T_SIGNED_BITS_MAX, SCM_T_SIGNED_BITS_MIN, SCM_T_BITS_MAX):
Likewise.
(SIZEOF_SCM_T_BITS): Remove.
