/* Attributes of the selected architecture:
The following four macros define specific aspects of the system. They
are defined as strings, or specifically undefined:
IMPLEMENTATION_MACHINE machine type
IMPLEMENTATION_CPU cpu type
IMPLEMENTATION_OS operating system
IMPLEMENTATION_FS file system
Big endian vs. little endian:
BIGENDIAN defined to 1 to denote bigendian systems
Alignment:
DOUBLE_ALIGN defined to 1 to force doubles to be aligned on
an even S2CINT boundary
Macro expansion:
NEED_MACRO_ARGS defined to 1 to declare a macro like X() as
X(dummy)
The types S2CINT and S2CUINT are defined to be signed and unsigned integers
that are the same size as pointers. This is the basic "word" used by
Scheme->C.
The machine state when a continuation is created is captured in the
sc_jmp_buf data structure.
STACKPTR( x ) is a define that stores the address of the stack pointer
in x.
Unix flavors:
POSIX POSIX.1 compliant
SYSV System V or derivative
SYSV4 System V release 4 (also define SYSV, POSIX)
