The @code{ISO_FORTRAN_ENV} module provides the following scalar default-integer
named constants:
@table @asis
@item @code{CHARACTER_STORAGE_SIZE}:
Size in bits of the character storage unit.
@item @code{ERROR_UNIT}:
Indentifies the preconnected unit used for error reporting.

an input/output statement if an end-of-file condition occurred.

an input/output statement if an end-of-record condition occurred.

The @code{ISO_C_BINDING} module provides the following named constants of the
type integer, which can be used as KIND type parameter. Note that GNU
Fortran currently does not support the @code{C_INT_FAST...} KIND type
parameters (marked by an asterix (@code{*}) in the list below).
The @code{C_INT_FAST...} parameters have therefore the value @math{-2}
and cannot be used as KIND type parameter of the @code{INTEGER} type.
