* Move clang/gcc options into makefile-header. This puts all of the shared options into a single place so that we can easily update it. * Add -fwrapv to the clang/gcc command lines. This is a step along the way to fixing interlisp/medley#90. Enabling `-fwrapv` will let overflow checks that rely upon undefined behavior to work correctly. Without this, with modern versions of clang and gcc, the overflow checks in the C code are eliminated by the compiler, resulting in incorrect behavior on the part of Maiko. See the linked bug for details and discussion. Hopefully, this usage of `-fwrapv` will go away once we're using the correct compiler builtins to detect and handle overflow correctly.

This is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display and disk etc.
There are make file fragments that include all the flags and variables you have to set for each hardware/OS target.
- cd to the "bin" directory
- have "." on your PATH
- do "./makeright x"
It will (attempt to) detect the OS-type and cpu-type, and put together the makefile parts that it needs. It will build in ../ostype.cputype-x (for the .o files) and ../ostype.cputype for the executables.
