# Define these for your system as follows:
#	-DRTL		To create a run-time library only (no
#			interactive front end).
#	-DRECKLESS	To turn most SCM error schecking off.
#	-DCAUTIOUS	To always check the number of arguments to
#			interpreted closures.
#	-DIO_EXTENSIONS	To get primitives such as chdir, delete-file,
#			file-opisition, and pipes.
#	-DPROMPT=\"..\"	To change the default prompt.
#	-DFLOATS	To turn on support for inexact numbers.
#	-DSINGLES	To use single-precision floats (if a float is
#			the same size as a long).
#	-DSINGLESONLY	To make all inexact real numbers to be single
#			precision.  Only useful if SINGLES is also
#			defined.
#	-DGC_FREE_SEGMENTS
#			To have all segments of unused heap be freed
#			up after garbage collection.  Do not define if
#			you never want the heap to shrink.
#	-DTICKS		If you want the ticks and ticks-interrupt
#			functions defined.
#	-DBRACKETS_AS_PARENS
#			To have square brackets read as parentheses
#			in forms.
#	-DMEMOIZE_LOCALS To speed up most local variable references.
#			You will need to remove this and recompile
#			eval.c if you use very large or deep
#			environments (more than 4095 bound variables
#			in one procedure).
#	-DENGNOT	To use engineering notation instead of
#			scientific notation.
#	-DSICP		To make SCM more compatible with the Scheme used
#			in Abelson & Sussman's book.
#	-DSTACK_LIMIT	To limit the maximum growth of the stack (you
#			almost certainly don't want this).
# See also `scmconfig.h' and `scmfig.h'.
