Ugh. 49 50 <inttypes.h> defines a variety of things, some of which we 51 probably do not want. So we don't want to include it here. 52 53 Luckily we can just declare strtoll and strtoull with the 54 __asm extension which effectively renames calls at the 55 source level without namespace pollution. 56 57 Also note that the compiler defines _INCLUDE_LONGLONG for C++ 58 unconditionally, which makes intmax_t and uintmax_t long long 59 types. 60 61 We also force _GLIBCXX_USE_LONG_LONG here so that we don't have 62 to bastardize configure to deal with this sillyness. */ 63namespace std 64{ 65#ifndef __LP64__ 66 __extension__ extern "C" long long strtoll (const char *, char **, int) 67 __asm ("__strtoll"); 68 __extension__ extern "C" unsigned long long strtoull (const char *, char **, int) 69 __asm ("__strtoull"); 70#else 71 __extension__ extern "C" long long strtoll (const char *, char **, int) 72 __asm ("strtol"); 73 __extension__ extern "C" unsigned long long strtoull (const char *, char **, int) 74 __asm ("strtoul"); 75#endif 76} 77 78#define _GLIBCXX_USE_LONG_LONG 1 79 80// HPUX on IA64 requires vtable to be 64 bit aligned even at 32 bit 81// mode.
