Unfortunately this is not possible. You have to use #. :
(sysname (c-array char #._SYS_NMLN))

No, an interface for doing that is missing. The only way to do that now
is to pack the C code into a separate C file which you then link against.
An unportable way of outputting C code directly (between functions) is
(format compiler::*coutput-stream* ...stuff...)
