This is for systems without dynamic loading support. Use
FOREIGN_FLAG=
FOREIGN_FILE=dummy-foreign.h
For generic systems you should only need to decide whether to turn on
the ANSI and IEEE flags. If your system has an ansi C compiler, use
ANSI_FLAG = -DANSI
Otherwise use
ANSI_FLAG =
If your system has IEEE 754 arithmetic and provides the functions
`finite' and `isnan' in its math library (or some other library),
use
IEEE_FLAG = -DIEEEFP
Otherwise use
IEEE_FLAG =
The configure script may be able to set this up for you.
If you want dynamic loading and have a system that is not directly
supported in the machines directory, check whether your system has
shared libraries and, if so, whether there is a programmer's interface
that let's you load a library and find a symbol's address in the
library. If so, it should not be too hard. Look at what is done for
hpux and for alpha, irix and solaris.
