* 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.
