unicodectype.c now fails to compile, because ch is declared const, and then assigned to. Tim has (apparently) had similar problems, but in his case the compiler just gives a warning, rather than an error.:
<sample of many similar> cc: Error: Objects/unicodectype.c, line 67: In this statement, "ch" has const-qualified type, but occurs in a context that requires a modifiable lvalue. (neednonconst) ch += ctype->title; --------^ cc: Error: Objects/unicodectype.c, line 69: In this statement, "ch" has const-qualified type, but occurs in a context that requires a modifiable lvalue.
