implementation of evaluator specific memoization codes and special
constants like #f, '() etc. ('flags'), which are not evaluator
specific. The goal is to remove definitions of evaluator
memoization codes completely from the public interface. This will
make it possible to experiment more freely with optimizations of
guile's internal representation of memoized code.

memoization codes.

guile's special constants.

(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)

rewrite of handling of real and complex numbers.
(SCM_FLOATS, SCM_SINGLES): These #ifdef conditionals have been
removed along with the support for floats. (Float vectors are
still supported.)
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
removals from Dirk Hermann.
* alist.c: Rename formals to match the parameter names in the
documentation, updates to documentation. Thanks Dirk Hermann!
* scm_validate.h: Added SCM_VALIDATE_THREAD.
* *.c: Remove SCM_NIMP(X) when it is an extraneous pre-test given
that SCM_FOOP macros all now include SCM_NIMP in their expansion.
This simplifies lots of code, making it far more readable.
