* lang.opt: Add Wcharacter_truncation option.
* options.c (gfc_init_options): Initialize
gfc_option.warn_character_truncation to zero.
(gfc_handle_option): Add case for OPT_Wcharacter_truncation.

* resolve.c (resolve_code): Use the code->expr character length
directly to set length of llen.

* decl.c (gfc_in_match_data, gfc_set_in_match_data): New
functions to signal that a DATA statement is being matched.
(gfc_match_data): Call gfc_set_in_match_data on entry and on
exit.
* gfortran.h : Add prototypes for above.
* expr.c (check_init_expr): Avoid check on parameter or
variable if gfc_in_match_data is true.
(gfc_match_init_expr): Do not call error on non-reduction of
expression if gfc_in_match_data is true.

* decl.c (gfc_set_constant_character_len): Add boolean arg to
flag array constructor resolution. Warn if string is being
truncated. Standard dependent error if string is padded. Set
new arg to false for all three calls to
gfc_set_constant_character_len.
* match.h : Add boolean arg to prototype for
gfc_set_constant_character_len.
* gfortran.h : Add warn_character_truncation to gfc_options.
* options.c (set_Wall): Set warn_character_truncation if -Wall
is set.
* resolve.c (resolve_code): Warn if rhs string in character
assignment has to be truncated.
* array.c (gfc_resolve_character_array_constructor): Set new
argument to true for call to gfc_set_constant_character_len.

* trans-decl.c (gfc_sym_mangled_function_id): Module, external
symbols must not have the module name prepended.
