I don't like adding another << >> SvStream operator for bool. If there
are places which would break on converting BOOL to bool because they're
getting streamed to disk via SvStreams, then I think I'd prefer to see
those specific BOOLs converted to sal_uInt8.
I see we also have a << >> SvStream operators for "long" which is
another disaster seeing as a long is either 32bits of 64bits in size
depending on platform. Anything streaming a long to disk is probably
broken and depending on a long being 32bit, or is hopefully only being
used for some temporary scratch format which could be replaced by
Here's another to-do for someone. Remove the long << >> SvStream
operators and find what's using them and lets consider if we can remove
them too as they are a ticking timebomb.
