The calls can be updated by incrementing the argument count of build_call_expr_loc, and adding the size argument. Then you can't use os_error, which is non-variadic. You can either use one of the existing (variadic) routines, such as runtime_error, or create some os_error_varargs (basically create the gfor_fndecl_XXX in trans-decl.c and use it as argument of build_call_expr_loc). If you create a new declaration, you'll have to write the corresponding code in libgfortran. Does it sound like it's worth it?
