I'm curious about what would happen should 'sslVersion' be set to
'tlsv1.0' (or a value that doesn't belong to the possible values) and
'LIBCURL_VERSION_NUM' be inferior to '0x072200'.
Since we wouldn't go through any 'if' and would also skip the 'else'
case, wouldn't we have a silent 'unsupported ssl version: using
default' ?

So I think that the 'else' case should be outside of the '#if [...]
#endif'.

Thanks,
