40 | /* HP-UX, for reasons unknown choose to use a different name for |
41 | the string to [unsigned] long long conversion routines. | |
42 | ||
43 | Furthermore, instead of having the prototypes in stdlib.h like | |
44 | everyone else, they put them into a non-standard header | |
45 | <inttypes.h>. Ugh. | |
46 | ||
47 | <inttypes.h> defines a variety of things, some of which we | |
b6e22016 | 48 | probably do not want. So we don't want to include it here. |

50 | Luckily we can just declare strtoll and strtoull with the |
51 | __asm extension which effectively renames calls at the | |
52 | source level without namespace pollution. | |
53 | ||
54 | Also note that the compiler defines _INCLUDE_LONGLONG for C++ | |
55 | unconditionally, which makes intmax_t and uintmax_t long long | |
56 | types. | |
4585ae3d | 57 | |
3d7c150e | 58 | We also force _GLIBCXX_USE_LONG_LONG here so that we don't have |
4585ae3d | 59 | to bastardize configure to deal with this sillyness. */ |
