/* HP-UX, for reasons unknown choose to use a different name for
the string to [unsigned] long long conversion routines.
Furthermore, instead of having the prototypes in stdlib.h like
everyone else, they put them into a non-standard header
<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. */
