Well, yes Long_Integer is 64-bits, but long long in cpp is 128 bits which s=
ounds like a discrepancy to me. On OpenBSD it indicates C time_t should be =
changed from Long_Integer to somethinge else that is 128-bits.  All package=
s in Ada has "with Standard; use Standard;" which brings Integer etc. into =
scope. Long_Integer should be defined in the Standard package. Under help i=
n GPS it should be possible to find the Standard package.
