Subject: redirecting stderr/ stdout

Re error redirection.  If the preprocessor produces an error, say
because it cannot find an include file due to a typo, I find that it
quits with no visible error message;  compiling with -E oes not help,
though if I compile with E and redirect output to a file, as with

gcc -E prog.cc > temp

then the file "temp" DOES have usefule error messages in it.  This is
the kind of thing which confuses novices!  Incidentally, I have 1r2 in
the environment variable.  Is there a way of getting preprocessor
errors straight to the screen as with compiler messages?
