Thanks for the info. Is it OK to just require MSVC7, or should we
write a compatibility function for earlier versions? The nice thing
about _strtoi64 is that its interface is compatible with strtoll,
which means one can #define str_to_wgint to strtol, strtoll, or
_strtoi64, as appropriate for the platform.
One more question: how does one spell 64-bit constants in MSVC?
google seems to suggest nnnI64; how portable is that?
