c_type_print_varspec_suffix): Add cases for Fortran type codes. * eval.c (evaluate_subexp): For OP_ARRAY expressions in Fortran, call f77_value_literal_string instead. * f_exp.y: Include <string.h>, move include of parser-defs.h. (parse_number): Translate 'd' floats to 'e' so atof() works. (yylex): Remove unused variables. * f-lang.c: Include <string.h>. (get_bf_for_fcn): Remove unused variable. * f-typeprint.c (f_type_print_varspec_prefix, f_type_print_varspec_suffix): Remove unused variables, add cases to switch statements. (f_type_print_base): Remove unused variables. * f-valprint.c (gdbcore.h, command.h): Include. (f77_get_dynamic_lowerbound, f77_get_dynamic_upperbound): Call read_memory_integer with correct number of arguments. (f77_get_dynamic_upperbound): Call f77_get_dynamic_lowerbound with correct argument type. (f77_print_array): Removed unused array array_size_array. (f_val_print): Don't use a CORE_ADDR as a char *. * valops.c (value_cast): Handle COMPLEX and BOOL types. (value_assign): Handle Fortran literal string and complex values. (f77_cast_into_complex, f77_assign_from_literal_string, f77_assign_from_literal_complex): New functions.
