It is very hard to say something meaningful about these problems,
since they involve large programs and happen only ``sometimes''.
Perhaps if you could describe what is special about the times when the
problems do happen, it would help.
One possibility is that these problems are somehow due to conflicts
between names of temporary files used by the compiler driver. The
current versions of library functions which create temporary files
aren't 100% safe when several programs run concurrently. Perhaps you
run other instances of the compiler or other DJGPP programs which use
temporary files at the same time?

Once again, please try to understand what conditions cause `ls' to not
report some of the files.
