+ * Only OpenBSD/m88k is currently supported; other platforms (such as
+ * Motorola's SysV/m88k) could be supported with the following tweaks:
+ *
+ * - non-OpenBSD systems use an `outgoing parameter area' as part of the

+ * into account when adjusting the stack, in the assembly code.
+ *
+ * - the logic deciding whether a function argument gets passed through
+ * registers, or on the stack, has changed several times in OpenBSD in
+ * edge cases (especially for structs larger than 32 bytes being passed
+ * by value). The code below attemps to match the logic used by the
