You say you are using gcc, but that would be relevant to the Sun C++ 
compiler (see the R-admin manual, which also says that configure adds it 
where needed).  So which C++ compiler is this?  The symptoms do look as if 
you are mixing incompatible C and C++ compilers.

I don't have anything like as old components as you have, but igraph 
contains C++ errors and will not compile under the SunStudio 12 C++ 
compiler (reported to the maintainer a long time ago).  It did work for me 
just now using gcc/g++ 4.2.1 and R 2.6.1 patched.

Since no changes are needed to compile under gcc, this suggests you are 
not using gcc's C++ compiler.
