4Subject: [PATCH] Compile with libc's without cispeed / cospeed
5
6Some libc implementations (e.g. musl) do not define the cispeed and
7cospeed struct termios fields. So we have to check the
8_HAVE_STRUCT_TERMIOS_C_ISPEED and _HAVE_STRUCT_TERMIOS_C_OSPEED
9macros. If not defined, we disable custom baudrate support.
