The deftype expansion functions now take two parameters, the type argument and an environment. More precisely, for an atomic type 'x the type argument for the expansion function is given by '(x) while for a non-atomic type '(x y z) it is given by '(x y z). This also fixes the value of &whole parameters in deftype lambda lists. The new behaviour is consistent with SBCL and CCL. Fixes #750 |

ECL stands for Embeddable Common-Lisp. The ECL project aims to produce an implementation of the Common-Lisp language which complies to the ANSI X3J13 definition of the language.
The term embeddable refers to the fact that ECL includes a Lisp to C compiler, which produces libraries (static or dynamic) that can be called from C programs. Furthermore, ECL can produce standalone executables from Lisp code and can itself be linked to your programs as a shared library. It also features an interpreter for situations when a C compiler isn't available.
ECL supports the operating systems Linux, FreeBSD, NetBSD, DragonFly BSD, OpenBSD, Solaris (at least v. 9), Microsoft Windows (MSVC, MinGW and Cygwin) and OSX, running on top of the Intel, Sparc, Alpha, ARM and PowerPC processors. Porting to other architectures should be rather easy.
