Yes but a VCL BPL can reasonably assume that the thing calling it is VCL
compatible code. Remy isn't saying that it won't work - he's saying that it
depends on who is calling the DLL.

If you are writing a DLL that will absolutely, without question, only be
called by your own code generated by the same compiler with the appropriate
switches then you can do it.

The issue is that one of the main reasons for having DLLs, one of their
main features, is that they aren't supposed to be tied to a specific EXE
like that. By implementing your project that way you are producing a
non-standard DLL.

It is generally best to consider a DLL as a separate executable. Assume
that the only thing that can safely cross the boundary is POD (Plain Old
Data - nothing you can't create in 'C'). I'd even think twice about letting
floating point numbers out of a DLL frankly.
