exactly. stdout is a pointer to a structure for c-style buffered I/O.
how this is done internally, is different between operating systems
(sometimes even differently between different releases of the same
operating systems) and deliberately hidden from the user/programmer.
the internal interface is defined in the header files (e.g. in
/usr/include/), therefore you always have to compile c code 'against' a
_matching_ set of header files. since i am not aware of a freebsd intel
fortran compiler, i assume you are using the 'linux compatibility
module' and the intel linux fortran compiler, right?  therefore you need
to compile the sysdepend.c with a (matching e.g. redhat 7.x or 8, or the
matching intel icc) linux compiler.

well, is there a special reason (except for hack value) that you cannot
use the linux binaries on your freebsd machine? you could try a
statically linked binary from your redhat 8 machine.

take care,
