Subject: [PATCH] ada: include header to declare isalpha in adaint

A vxworks-specific part of adaint.c calls isalpha without including
ctype.h.  gcc-14 rejects calls of undeclared functions.  Include the
required header file when compiling for vxworks.

gcc/ada/ChangeLog:

	* adaint.c [__vxworks]: Include ctype.h.
