Errrrm... it used to be that way a (not so) long time ago; see this
thread on the mailing list:
https://lists.nongnu.org/archive/html/igraph-help/2009-01/msg00119.html
However, I have just checked the source code and igraph_integer_t is
now typedef'd to an int so this is probably not the case any more.
