Not really, although fpc-devel might be more appropriate.

Yes, I was only talking about the generated code, not about the
compiler sources themselves. A simple example is in case you use
Internally, this is replaced by
The reason is that textpara could be a function call, and in that
case it must be called only once rather than thrice (and yes,
internally the compiler can take the address of function call
results, and no, as a programmer you are not allowed to do that :)
