+Subject: [PATCH] Compile with libc's without cispeed / cospeed
+
+Some libc implementations (e.g. musl) do not define the cispeed and
+cospeed struct termios fields. So we have to check the
+_HAVE_STRUCT_TERMIOS_C_ISPEED and _HAVE_STRUCT_TERMIOS_C_OSPEED
+macros. If not defined, we disable custom baudrate support.
+
+[baruch: backported from upstream master to 3.1]
