Comment (by dimpase):
Is it assumed in libGAP that GAP long integers are GMP/MPIR integers? For
there is the following comment in the patch, in
`sage/libs/gap/element.pyx`, lines 1150-2:
{{{
An immediate integer is one that is stored as a C integer, and
is subject to the usual size limits. Larger integers are
stored in GAP as GMP integers.
}}}
Or it actually just calls the appropriate GAP long integer functions?
Note that GAP itself allows for different long integer backends, e.g. it
has its own implementation of them, used exclusively before version 4.5,
although Sage does not use this.
Whatever it is, it should be possible to discover without reading the full
source.
