guile-2.0.0 enum syntax fix

[David Fang]

Hi guilers,
	In "libguile/array-handle.h", line 84 (or near), there's a stray 
comma after the last enum value definition, SCM_ARRAY_ELEMENT_TYPE_LAST, 
that triggers errors in some ANSI-strict C and C++ compilers.  (e.g. gcc 
-ansi -pedantic-errors).
	Could the trailing comma be removed?  I've patched it out locally 
and tested it, and it is safe.  Let me know if you need the (trivial) 
patch.
        Thanks!

Fang
