[Ecls-list] Important fixes

[Juan Jose Garcia-Ripoll]

* Errors fixed:

+ Methods have a hash table for caching effective methods. ECL now restricts 
the size of these tables to 512 different combinations.

+ References to structure slots with (safety 0) would lead to wrong C code.

+ Syntax error in the C code from an assignment like (setf 
*my-special-variable* some-value) when compiled with (safety 0).

The fixes are both in CVS and in the "Experimental patches" which you can 
retrieve from http://ecls.sf.net (Navigation menu to the left).

Regards,

Juanjo
