439e35da61 Check for valid "rest" parameters in parameter lists 
Checks for invalid parameter names and duplicate parameters were
being performed on parameter lists, but these checks were not
considering any rest parameters.  This means that

  ((lambda (x . x) x) 'foo 'bar)   =>  foo
  ((lambda (x . 0) x) 'foo 'bar)   =>  foo
  ((lambda (x . #t) x) 'foo 'bar)  =>  foo
  ((lambda 0 'foo))                =>  foo
  ((lambda #t 'foo))               =>  foo

and so on.  Now these all produce errors.

b25e46b11b Introduced a second version of sexp_double_to_ratio, named 
sexp_double_to_ratio_2, which converts without introducing
round-off errors the way sexp_double_to_ratio does when it
multiplies by 10.

Changed sexp_inexact_to_exact to use this new function when
a non-zero fractional part of the input exists.

e092923aac Win32: Fix win32 port 
Try to fix win32 port. Now it runs both on Win32/Win64.

Win64 port currently depends on 128bits arithmetic thus it does not run on
MSVC.

Makefile now have EXCLUDE_POSIX_LIBS knob to exclude posix related library
from build.

Introduce msys PLATFORM for Makefile.detect to use MSYS's POSIX
emulation layer. It is intended for linking against MSYS tools; it is
not for embedding to Win32 applications.

2e481d57e9 Non-strict top-level identifier matching now works if the identifier 
is bound in only one of the environments.  This is necessary in the
case where a library uses an unbound keyword (e.g. "with" in (chibi
loop)), but you want to use it along with a binding for the
keyword (e.g. "with" in (chibi show)).  The alternative to work with
the current logic is to always require such keywords to be bound, in
this case to add a dummy "with" auxiliary syntax binding to (chibi
loop), however this doesn't seem any safer than the new logic, and the
whole point of the feature is convenience.  Fixes issue #221.
