I downloaded the NEC source code from http://www.qsl.net/m5aiq/nec.html

My compiler is GNU FORTRAN (g77).

The compile error is: "Reference to intrinsic function 'SECNDS' as if
it were a subroutine at (^)"

My FORTRAN is a bit rusty, before I go climb that hill, can a wise old
coder offer a fix?

It's used to work out execution time

There is a call to a subroutine SECNDS . SECNDS is a built in function
in gnu FORTRAN that interrogates the computer clock

http://gcc.gnu.org/onlinedocs/gcc-4....an/SECNDS.html

remove the "CALL" and it should work
