it is not

OK, thanks for the clarification.

Another issue I stumbled across: There are numerous places (well, some 10) were something like the following is done

int var = var; char *othervar = othervar;

Here this leads to Compiler warnings 'variable "var" is used before its value is set' on NonStop. This self-initialization seems to be a GCC extension (?), but even gcc has a -Winit-self option to warn about this. Shouldn't that better be like the following?

int var = 0; char *othervar = NULL;

What is the reason for using that self-init stuff? I don't think it is really portable, is it?

Bye, Jojo
