Patch installed to libiberty/cplus-dem.c for warning nits.

[Kaveh R. Ghazi]

I installed the following obvious patch to fix these warning nits from
cxxmain.c (which is a link to libiberty/cplus-dem.c):

 > cxxmain.c:931: warning: function declaration isn't a prototype
 > cxxmain.c:998: warning: subscript has type `char'
 > cxxmain.c:999: warning: subscript has type `char'
 > cxxmain.c:1013: warning: subscript has type `char'
 > cxxmain.c:1036: warning: subscript has type `char'

	* cplus-dem.c (grow_vect): Prototype.
	(ada_demangle): Cast the arg of ctype macros to unsigned char.
