+ fix a null-pointer check in _nc_format_slks() in lib_slk.c, from 20070704 changes. + modify _nc_find_type_entry() to use hashing. + make CCHARW_MAX value configurable, noting that changing this would change the size of cchar_t, and would be ABI-incompatible. + modify test-programs, e.g,. test/view.c, to address subtle differences between Tru64/Solaris and HPUX/AIX getcchar() return values. + modify length returned by getcchar() to count the trailing null which is documented in X/Open (cf: 20020427). + fixes for test programs to build/work on HPUX and AIX, etc.
