Compiles fine for me using 
g++ (GCC) 3.4.4 (cygming special) (gdc 0.12, using dmd 0.125)

Check that ex04-01.cpp is not empty (it shouldn't be) and is readable:
$ wc -l ex04-01.cpp
39 ex04-01.cpp

I can reproduce the problem like this:

  echo "" > junk.cpp && g++ junk.cpp

Perhaps you've opened the source with a brain-damaged editor that
opens the file for writing and keeps it open? [Files opened for
writing without FILE_SHARE_READ mode can't be read by other
processes, I think.]
