What can cause this? Thank you!

Answer 1

It's failing because the code configure is using to determine the size of the type is invalid. It is the return without expression in line 7832 that makes configure fail. See bug #579689 for details.

./configure:

7829 int main() {
7830
7831                      int a[sizeof (void*) == $size ? 1 : -1];
7832                      return;
7833
7834 ; return 0; }
