[fpc-pascal] H2pas tool vs others, C header translation

[Dmitry Boyarintsev]

Is 2 neither true, nor false? 3? 4?

If false is zero,
Then true is not false.

Also C doesn't have a boolean type per se. Iirc it was introduced in some
version of c++ standard.

In C it's very strange to see code like that:

If (b==1)

It's always
If (b)
Or
If (!b)
