47 Furthermore, instead of having the prototypes in stdlib.h like
48 everyone else, they put them into a non-standard header
51 <inttypes.h> defines a variety of things, some of which we
52 probably do not want. So we don't want to include it here.
54 Luckily we can just declare strtoll and strtoull with the
55 __asm extension which effectively renames calls at the
56 source level without namespace pollution.
58 Also note that the compiler defines _INCLUDE_LONGLONG for C++
59 unconditionally, which makes intmax_t and uintmax_t long long
62 We also force _GLIBCXX_USE_LONG_LONG here so that we don't have
63 to bastardize configure to deal with this sillyness. */
