This indicates that the errors and warnings of the compiler are getting
sent to standard error, not standard output.  Thus, the ">" operator
does not redirect them, as it only redirects standard output.

To redirect standard error in the DOS shell, use the "2>" operator
instead of the ">" operator, like so:

gfortran function.f90 2>file

This is a DOS shell thing that has nothing to do with gfortran, really,
but is something that occurs for any program that prints its output to
the standard error stream.
