[igraph] compilation failed at trunk revision #2445

[Minh Nguyen]

Hi folks,

I checked out trunk revision #2445 and configured it as follows

./configure --prefix=/scratch/mvngu/usr --disable-graphml
--disable-gmp --disable-glpk --enable-gcc-warnings

Doing make resulted in a compilation failure. Here's a relevant snippet:
