I agree, with the caveat that each version of Lazarus tends to work with
a fairly tight range of compiler versions.
I can't give accurate version numbers without spending time looking
things up, but somewhere around 2.6.x FPC started assuming Unicode
handling that was documented but unimplemented in NT4. At that point
there was a simple patch which could be applied to the RTL (?) to fix
it, but realistically it made that version the last that supported NT
(and I suspect '98).
I appreciate that some people have no choice but to use NT4, typically
because it is running on rack-mounted "industrial computers" or similar.
But I'd suggest that wherever there is a choice it would be better to
look at W2K if at all possible, which while still well out of support at
least doesn't "self destruct" like XP. At the very least, use W2K for
development and then test on NT4.
18803 is relevant but might not be the only issue.
