dnl Look for a 64 bit data type. It is necessary to check both C and C++
dnl compilers.
dnl
dnl A better implementation would check whether or not AC_PROG_CC and
dnl AC_PROG_CXX have been invoked and only test the appropriate
dnl compiler.
dnl
dnl When cross-compiling, default to long long on the assumption that
dnl gcc/g++ must be used and long long is likely to be the 64 bit data
dnl type. This is not guaranteed, but sufficiently likely to meet
dnl the requirements for the time being. The CHECK_SIZEOF() macro
dnl might be another way to get the desired information.
