* src/common/serial.c: Changed all calls to cyg_drv_cond_signal() to cyg_drv_cond_broadcast(). Removed comment asking whether this matters: it does. * include/serialio.h: Added includes of pkgconf files so that the ifdefs in this file work properly. * include/serial.h: Added include of devtab.h to fix compile error.
