Is "fileno" defined as a macro on your system?  If so, what is it
expanding to?

Can you please add -save-temps to the compile command above and send
me the resulting file-io.ii file?  You don't need to run configure with
-save-temps in CXXFLAGS, just cd to the src subdirectory in your build
tree and cut and paste the g++ command above and add -save-temps to
it.
