/usr/local/include/c++/4.8.2/exception(97): error: expected an identifier..?

Hello,

When I build a project, I get the following error during compilation

/usr/local/include/c++/4.8.2/exception(97): error: expected an identifier

I have not changed the (linux) system

When I exclude the source file the compiler stalls on, it manages to continue

When I include an empty shell of function within the particular source file, I still get the error

Any idea why the error, or even what the error is?
