This header can be included into both Fortran and C.

This file defines various code values that need to be exported
to predefined Fortran standard modules as well as to C/C++
code in the compiler and runtime library.
These include:
 - the error/end code values that can be returned
   to an IOSTAT= or STAT= specifier on a Fortran I/O statement
   or coindexed data reference (see Fortran 2018 12.11.5,
   16.10.2, and 16.10.2.33)
Codes from <errno.h>, e.g. ENOENT, are assumed to be positive
and are used "raw" as IOSTAT values.
