* Makefile.in (.l.c): Do conversions of names of alloc and free
functions that are done for .y.c files, plus special one
for yy_flex_realloc.  Also, correct missing-file tests here.
* ada-lex.l (malloc, free): Remove macros.
(resize_tempbuf): Use "realloc"; rely on sed changes to convert to
xrealloc.
(ada_flex_use): Dummy definition to remove warnings about unused
functions.
* ada-exp.y (dummy_string_to_ada_operator): Temporary definition
to suppress warning.
