Yes, there is. I think it should work by setting the environment  
variables called "CC" and "CXX" to the appropriate C and C++ compilers  
when invoking ./configure and make as follows:

CC=gcc-4.1 CXX=g++-4.1 ./configure
CC=gcc-4.1 CXX=g++-4.1 make

I'm not sure whether this really works, but I think it should.  
Otherwise, you can simply call ./configure as usual, then replace the  
variables called CC and CXX in the generated Makefile to point to the  
appropriate gcc version. I can't help you more right now, since I'm on  
holiday and I don't have access to a Debian amd64 box, but if you  
still have problems, drop me a mail next week.
