+   <inttypes.h>.  Ugh.
+
+   <inttypes.h> defines a variety of things, some of which we 
+   probably do not want.  So we don't want to include it here.
+
+   Luckily we can just declare strtoll and strtoull with the
+   __asm extension which effectively renames calls at the
+   source level without namespace pollution.
+
+   Also note that the compiler defines _INCLUDE_LONGLONG for C++
+   unconditionally, which makes intmax_t and uintmax_t long long
+   types.
+
+   We also force _GLIBCXX_USE_LONG_LONG here so that we don't have
+   to bastardize configure to deal with this sillyness.  */
