        * trans.h (gfor_fndecl_internal_malloc, gfor_fndecl_internal_malloc64,
        gfor_fndecl_internal_free): Remove prototypes.
        (gfor_fndecl_os_error, gfc_call_free, gfc_call_malloc): Add prototypes.
        * trans.c (gfc_call_malloc, gfc_call_free): New functions.
        * f95-lang.c (gfc_init_builtin_functions): Add __builtin_free
        and __builtin_malloc builtins.
        * trans-decl.c (gfor_fndecl_internal_malloc,
        gfor_fndecl_internal_malloc64, gfor_fndecl_internal_free): Remove.
        (gfor_fndecl_os_error): Add.
        (gfc_build_builtin_function_decls): Don't create internal_malloc,
        internal_malloc64 and internal_free library function declaration.
        Create os_error library call function declaration.
        * trans-array.c (gfc_trans_allocate_array_storage,
        gfc_trans_auto_array_allocation, gfc_trans_dummy_array_bias,
        gfc_conv_array_parameter, gfc_duplicate_allocatable): Use
        gfc_call_malloc and gfc_call_free instead of building calls to
        internal_malloc and internal_free.
        * trans-expr.c (gfc_conv_string_tmp): Likewise.
        * trans-stmt.c (gfc_do_allocate, gfc_trans_assign_need_temp,
        gfc_trans_pointer_assign_need_temp, gfc_trans_forall_1,
        gfc_trans_where_2: Likewise.
        * trans-intrinsic.c (gfc_conv_intrinsic_ctime,
        gfc_conv_intrinsic_fdate, gfc_conv_intrinsic_ttynam,
        gfc_conv_intrinsic_array_transfer, gfc_conv_intrinsic_trim): Likewise.

        * runtime/memory.c (internal_malloc, internal_malloc64,
        internal_free): Remove.
        * runtime/error.c (os_error): Export function.
        * intrinsics/move_alloc.c: Include stdlib.h.
        (move_alloc): Call free instead of internal_free.
        (move_alloc_c): Wrap long lines.
        * libgfortran.h (os_error): Export prototype.
        (internal_free): Remove prototype.
        * gfortran.map (GFORTRAN_1.0): Remove _gfortran_internal_free,
        _gfortran_internal_malloc and _gfortran_internal_malloc64.
        Add _gfortran_os_error.
