The capability that curl (the tool) has to read, write and transfer
files larger than 2Gb.

Both are required to perform the three actions described above.

I highly suspect that an app that uses libcurl and provides its own
read, write or seek callbacks should be compiled with the same LFS
settings as libcurl.

If the app does not provide its own read, write or seek callbacks, the
app might probably use whatever LFS setting the app wishes. But it is
not absolutely clear that this can always be done on all systems.

So we should listen very carefully to what others have to say or
report on this matter.
