Ah, but that is actually not as confusing as it looks at first. I put the code to the MinGW port of gcc 3.4.5, and since I did not enable the -std=c99 flag at the time, it gave the warning "ISO C90 forbids variable-size array `type name'". It then became clear that just as int[N] is the type of an int array of size N, int[nnode+1] is an int array of size nnode+1, even if nnode is a variable, assuming that the variable length arrays feature is available.

I never ran it through a compiler except now and what's interesting is that the C89 one works for me while the C99 one gives errors. Oh well live and learn.
