g++ 4.3.2-4 problem with typeof

[anon]

Hello,

I am trying to upgrade the compiler from 4.1.3 to 4.3.2, and I am 
getting next errors:
filename.cpp: line number: sorry, unimplemented: mangling typeof, use 
decltype instead
What I find strange, is why it doesn't happen with g++ 4.1.3

I have this in several files, and the line number is always the last 
line in the file. In these files, typeof is not used. By the way, it 
wasn't me who wrote these files.

Since the project is big, I have no idea where to start looking and I 
can not write an example that demonstrates this.

Can anyone help to solve this problem? Or at least to suggest how to 
proceed?
