subrange.
* f-lang.h (enum f90_range_type): New enumeration type to identify
F90 subrange type.
* f-exp.y (yyparse): Add support for parsing F90 subrange and
change substring parsing to subrange parsing.
* parse.c (operator_length_standard): Set the operator length
and args number for OP_F90_RANGE.
* eval.c (evaluate_subexp_standard): Add code to evaluate F90
array section and substring.
(value_f90_subarray): New function to evaluate F90 array section.
(evaluate_subexp_standard): Delete label op_f77_substr and its code
because the logic is implemented by function value_f90_subarray now.
f77_create_literal_complex_type.
* valops.c (f77_value_literal_string, f77_value_substring,
f77_value_literal_complex): Use xmalloc not malloc.
* valops.c (f77_value_literal_string, f77_value_substring):
Make addr char * not CORE_ADDR.
* value.h (struct value): Add new field literal_data of aligner union.
(VALUE_LITERAL_DATA): Use it.
* f-lang.h: Declare find_common_for_function.
* value.h, valops.c: Split VALUE_SUBSTRING_START into memaddr and
myaddr fields of a union. Don't overload it with the frame field
(not sure this is necessary; I'm not sure what lval_* codes
VALUE_SUBSTRING_* can be used with).
(fmbutt@engage.sps.mot.com).
* Makefile.in: Add Fortran-related files and dependencies.
* defs.h (language_fortran): New language enum.
* language.h (_LANG_fortran): Define.

* gdbtypes.h (TYPE_CODE_COMPLEX, TYPE_CODE_LITERAL_COMPLEX,
TYPE_CODE_LITERAL_STRING): New type codes.
(type): New fields upper_bound_type and lower_bound_type.
(TYPE_ARRAY_UPPER_BOUND_TYPE, TYPE_ARRAY_LOWER_BOUND_TYPE,

macros.
(builtin_type_f_character, etc): Declare.

* f-lang.h: New file, Fortran language support declarations.
* f-typeprint.c: New file, Fortran type printing.
* f-valprint.c: New file, Fortran value printing.
* eval.c (evaluate_subexp): Add code for new expression opcodes,
fix wording of error message.
* gdbtypes.c (f77_create_literal_complex_type,
f77_create_literal_string_type): New functions.
* language.c (set_language_command): Add Fortran info.
