I tried also with an older version of gcc (4.8.2) and got the same
problem in different source file, this time on genconstants.c. Check
the logs:

As you can see the GCC sources are tried to be compiled using 'g++', not
'gcc' as it
happened in the gcc-3 - early gcc-4 times!
If your C++ compiler doesn't understand the current sources, then please
try adding :
--disable-build-with-cxx
onto the GCC configure command. With gcc-4.8.2 this should still work
but I'm not
sure... Used it a couple of times with gcc-4.1.2 as the system GCC -
neither it worked
with newer GCC sources. Don't know whether this option was a temporary
workaround
for a while until everyone had a working system g++. Googling could help
to find the
history for this option. The net has examples for its use like :
