Any portable solutions for extracting the unsigned long long number?
The best effort I can provide is what's in Glib. They do what Sisyphus
suggests: represent big numbers as strings if necessary.

SvGUInt64 (SV *sv)

Many thanks for all the postings. I think we'll just use a string in the
Perl script as even this PORTABLE_STRTOULL cannot parse the value when
stored in scientific notation.
