Thanks for the report.
Which version of autoconf generated the configure that produced the
output you are questioning? And am I correct that this was on:

Did the configure.ac use the documented AC_TYPE_INT64_T and
AC_TYPE_UINT64_T macros, or is it using a home-brewed approach?
While you provided lots of details, you didn't provide quite enough for
me to know if this is something worth worrying about for the upcoming
2.67 release due later today.
