In a nutshell: the problem was caused by bliss_bignum.h which  
effectively contains two versions of a "big number" class (a class  
that is able to store arbitrarily large numbers). When you compile  
igraph with GMP support, the "big number" class is effectively a  
wrapper around GMP. However, when you disable GMP support, the class  
is implemented using various GNU functions (like fabsl) which seem to  
be missing under Cygwin. That's why you've seen an error.
