I stand corrected, you're right.

I did that in an attempt to fix compilation errors with yet another
compiler. Arnaud also warned me about this, by the way. I'll probably
redo this again, since I don't like the present situation either.

Apparently, it does. Yet I would prefer a more documented way of
handling this. For instance, by adhering to a certain C standard. At the
moment, as far as I can see we are not compliant to *any* version of the
standard (K&R, ANSI, C90 or C99).

That's also one of my worries here and initially also the reason for
submitting the first patch. We may not catch all problems there may be,
although every one found helps.
