[igraph] f2c compile error in trunk

[Paul Melis]

Hi,

I'm using 0.5.4 in a current project and wanted to check out 0.6 in 
advance and test some of the new routines. After cloning the 0.6-main 
bazaar branch and running ./bootstrap.sh and ./configure 
--prefix=<something>, a subsequent make gives the following error:

Any clues on how to resolve this?
