* c-typeprint.c (c_type_print_varspec_prefix,

Browse Source 
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.
