* Complete redesign of the operating-system interface. I/O is more
uniform and is able to take advantage of things like sockets, pipes,
ptys, etc. All I/O buffering is moved into the runtime system for
better performance with Scheme compiler code. Strong knowledge of
POSIX.1 should make porting to VMS easy once VMS supports POSIX.1.
* Change operating system conditionalizations to standard form
suggested by POSIX.1.
* Add FSF macros to support ANSI declarations.
* Add dynamic-stack package and obstacks.
* Provide higher-level utilities for parsing command line options.
* Instead of `Back_To_Eval', there is now a procedure
`abort_to_interpreter' which knows about everything that needs to be
cleaned up.
* Change names of some macros:
Pop STACK_POP
Push STACK_PUSH
Push_From STACK_LOCATIVE_PUSH
Pop_Into STACK_LOCATIVE_POP (similar)
Stack_Ref STACK_REF
Top_Of_Stack() STACK_REF(0)
Simulate_Popping STACK_LOC
Simulate_Pushing STACK_LOC (similar)
Stack_Distance STACK_LOCATIVE_DIFFERENCE (similar)
Pop_Primitive_Frame POP_PRIMITIVE_FRAME
Metering_Apply_Primitive PRIMITIVE_APPLY
Export_Regs_Before_Primitive EXPORT_REGS_BEFORE_PRIMITIVE
Import_Regs_After_Primitive IMPORT_REGS_AFTER_PRIMITIVE
* Sun assembler can't handle a constant used in "cmpaux-mc68k.m4", so
provide an option to rewrite that instruction as two instructions.
* Some compilers won't cast a function to an integer, so kludge around
it by mis-declaring the external function as an integer, taking it the
integer's address, and casting THAT to an integer.
* Move critical section code and termination code to their own files.
