[RFA]: Turn on initial Ada support in GDB

[Paul Hilfinger]

Aside from the documentation patch and the previously posted (and
approved) symtab.c patch, all that remains to give initial Ada support
is the following Makefile.in patch.  I will commit this tonight, as
well, but first wanted to give time for comment/protest: building with
Ada currently requires flex (I don't believe that lex has a guaranteed
and blessed way of substituting input sources cleanly at arbitrary
times).  Flex is perhaps not a universal utility, and I wondered if I
should also check in ada-lex.c (a practice we've discontinued for
yacc), or should assume that folks who build from the CVS sources are
expected to have flex.

        Turn on initial Ada support (mainly expression evaluation).
	
        * Makefile.in: (HFILES_NO_SRCDIR): Add ada-lang.h.
	(COMMON_OBS): Add ada-lang.o, ada-typeprint.o, ada-valprint.o.
	(YYOBJ): Add ada-exp.o.
	(SFILES): Remove ada-tasks.c.
	(rule .l.c): Generalize to not mention ada.
	(ada-lex.o): Remove (ada-lex.c is included by ada-exp.y).
	(ada-lang.o): Add dependencies on completer.h, gdb_obstack.h, 
	hashtab.h.
	(ada-valprint.o): Add dependency on gdb_string.h.
	(ada-exp.o): Add dependency on gdb_string.h.
