It compiles here under MSVC8, but I’m aware of at least one other report of
this problem. The current analysis is that if you compile in release mode, it
works OK, but the error appears in debug mode. If you try that, I would be
interested in the result.

Subject: [Flightgear-devel] Compile Error:cannot convert parameter 1 from
'FGPositioned *const ' to 'const FGPositioned::Type'
I checked out the fresh source code. When I compiled it with MSVC 8.0, I got
these error info.
I know the error comes from two lines in file "positioned.cxx".
Why I got these error info? Is the problem of MSVC 8.0 Compiler or FG source
code?
Please help me! Thanks.
/////////////////////////two lines in
positioned.cxx///////////////////////////////////////
l = lower_bound(it->second.begin(), it->second.end(), aFilter->minType(),
LowerLimitOfType());
u = upper_bound(l, it->second.end(), aFilter->maxType(), LowerLimitOfType());
