| 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. */ |
