2003-07-18  Nick Garnett  <[e-mail]>

	* cdl/hal_v85x_ceb_v850.cdl:
        Changed values for CYGNUM_HAL_RTC_NUMERATOR,
        CYGNUM_HAL_RTC_DENOMINATOR and CYGNUM_HAL_RTC_PERIOD to
        "default_value" from "calculated". This makes it easier
        to change these values globally.
        
2003-04-10  Nick Garnett  <[e-mail]>

	* include/pkgconf/mlt_v85x_v850_ceb_ram.ldi:

	suppressed" functionality.
