I've found that for alpha, the solution to the problem is to:

typedef unsigned long long gss_uint64;

in gssapi_krb5.h


so perhaps instead of:

#if defined(_WIN32)
typedef unsigned __int64 gss_uint64;
#else /*windows*/
#include <inttypes.h>
typedef uint64_t gss_uint64;
#endif

it should be:

#if defined(_WIN32) /* windows */
typedef unsigned __int64 gss_uint64;
#elsif ALPHA /*alpha*/
typedef unsigned long long gss_uint64;
#else /*not windows or alpha*/
#include <inttypes.h>
typedef uint64_t gss_uint64;
#endif


Where ALPHA is whatever macro is defined to note that this build is
happening on an alpha system.

Yeah, I found the unsigned long long definition in /usr/include for
u_int64_t:

db.h:typedef unsigned long long u_int64_t;

which I assume is the same as uint64_t. ;)

Yeah. Unfortunately, there is nothing defining uint64_t that I can find in
either /usr/include/ or /usr/include/sys/

:(

Yes, it is.


Alas, Tru64 4.0F has no such concept. (We're hoping to completely retire
Tru64 support once one last department moves off of it, which is why we've
not gone to the trouble of trying to upgrade to 5.x.)


It's not particularly difficult to fix up uintX_t, if that's the only
problem. Here's what we do for INN for int32_t and uint32_t; something
roughly equivalent should work:

dnl int32.m4 -- Find an appropriate int32_t and uint32_t.
dnl $Id: int32.m4,v 1.1 2003/12/26 03:23:28 rra Exp $
dnl
dnl The public macro exposed by this file is INN_TYPE_INT32_T. This macro
dnl locates the appropriate header files to include for int32_t and uint32_t
dnl or determines how to define those types, and then both includes the
dnl appropriate defines into the generated config.h.

dnl Used to build the type cache name.
AC_DEFUN([_INN_TYPE_CACHE], translit([ac_cv_sizeof_$1], [ *], [_p]))

dnl A modified version of AC_CHECK_SIZEOF that doesn't always AC_DEFINE, but
dnl instead lets you execute shell code based on success or failure. This is
dnl to avoid config.h clutter.
AC_DEFUN([_INN_IF_SIZEOF],
[AC_MSG_CHECKING([size of $1])
AC_CACHE_VAL(_INN_TYPE_CACHE([$1]),
[AC_TRY_RUN([#include <stdio.h>
main()
{
FILE *f = fopen("conftestval", "w");
if (!f) exit(1);
fprintf(f, "%d\n", sizeof($1));
exit(0);
}], _INN_TYPE_CACHE([$1])=`cat conftestval`, _INN_TYPE_CACHE([$1])=0,
ifelse([$2], , , _INN_TYPE_CACHE([$1])=$2))
])dnl
AC_MSG_RESULT($_INN_TYPE_CACHE([$1]))
if test x"$_INN_TYPE_CACHE([$1])" = x"$3" ; then
ifelse([$4], , :, [$4])
else
ifelse([$5], , :, [$5])
fi
])

dnl This is the beginning of the macro called by the user.
AC_DEFUN([INN_TYPE_INT32_T],
[

dnl Find a 32 bit type, by trying likely candidates. First, check for the
dnl C9X int32_t, then look for something else with a size of four bytes.
_INN_IF_SIZEOF(int, 4, 4, INN_INT32=int,
[_INN_IF_SIZEOF(long, 4, 4, INN_INT32=long,
[_INN_IF_SIZEOF(short, 2, 4, INN_INT32=short)])])

dnl Now, check to see if we need to define int32_t and uint32_t ourselves.
dnl This has to be done after the probes for an appropriately sized integer
dnl type so that we can pass that type to AC_DEFINE_UNQUOTED.
AC_CHECK_TYPE(int32_t, ,
[AC_DEFINE_UNQUOTED([int32_t], [$INN_INT32],
[Define to a 4-byte signed type if <inttypes.h> does not define.])])
AC_CHECK_TYPE(uint32_t, ,
[AC_DEFINE_UNQUOTED([uint32_t], [unsigned $INN_INT32],
[Define to a 4-byte unsigned type if <inttypes.h> does not define.])])
])
