The Borland 5.5 compiler's STL implementation does not properly copy comparators during assignment operations. For an example of how to work around this, see [http://public.kitware.com/cgi-bin/viewcvs.cgi/Rendering/vtkLabelHierarchy.cxx?r1=1.12&r2=1.13 vtkLabelHierarchy.cxx (rev 1.13)] | |||

'+' (plus) in the file name problem
- Borland linker when creating executable does not support '+' in the name.
- CMake solves this problem by creating object files by replacing '+' with '_p_'.
Broken streampos implementation
Using free bcc5.5.1.
#include <iostream>
int main()
{
std::streampos a = 9;
long c = 10;
if( a >= c )
{
std::cerr << "Impossible happen !" << std::endl;
}
else
{
std::cerr << "Seems resonable" << std::endl;
}
return 0;
}
On borland a >= c is true ...
According to the doc:
http://www.cplusplus.com/ref/iostream/streampos.html
This type describes a class to contain all the information needed to restore an arbitrary file-position indicator within a stream. It can be constructed from or casted to an integer offset value (streamoff).
There is a bug in the definition of std::streampos::operator<= where the implementation do the contrary of what expected.
STL multisets with comparators
The Borland 5.5 compiler's STL implementation does not properly copy comparators during assignment operations. For an example of how to work around this, see vtkLabelHierarchy.cxx (rev 1.13)
