Log Message:
Update to 1.4.9:
Changes since 1.4.8
1. src/slarray.c: superfluous call to SLclass_add_math_op removed
   (Michael Noble)
2. src/slang.c: foreach (NULL) using("next"){} foo (); caused _NARGS=1
   in foo.
3. src/slarrfunc.c: Fix to prevent sum(NULL) from causing a core-dump.
4. src/slimport.c: import (module, "") made equivalent to
   import(module,"Global");  This way, import(module, current_namespace())
   will work when the current namespace is anonymous.
5. src/slospath.c: Several users have requested that I add the ability
   to define a load path and use that path when loading interpreter
   files.  To this end, several new functions were added to the API:

       char *SLpath_get_load_path (void);
       int SLpath_set_load_path (char *path);
         /* Get and Set the path to be searched for files */
       int SLpath_get_path_delimiter (void);
       SLpath_set_path_delimiter (int delimiter);
         /* Get and set the character delimiter for search paths */
       int SLang_load_file_verbose (int verbose);
         /* if non-zero, display file loading messages */

   New intrinsics include:

       set_slang_load_path
       get_slang_load_path
       path_get_delimiter

   These functions, nor the intrinsics have an effect on applications
   that use SLang_load_file_hook or SLns_load_file_hook for loading
   files.  The change should be transparant to applications that use
   the stock load file mechanism.  The main difference is that if one
   attempts to load a file with no extension, e.g., "foo", but the
   file does not exist, then the interpreter will try to load the more
   recent of "foo.sl" and "foo.slc".

   See src/slsh.c for how the functions may be used.

6. slsh/slsh.c: Updated to use the new search path code outlined
   above.  Also, slsh is distributed with a collection of general
   purpose slang functions, including jed's provide/require functions.
   See slsh/README for more information.
7. doc/tm/cslang.tm: Modified the section describing the implemetation
   of intrinsic functions in an effort to clarify the discussion.
8. src/slang.c: tiny memory leak resulting from peephole optimzations
   added earlier found and fixed.
9. src/slarrmisc.c: new intrinsic: cumsum computes the cumulative sum
   of an array via the new SLarray_map_array function.
