2000-12-08  Jesper Skov  <[e-mail]>

	* src/vectors.S (cyg_scheduler_sched_lock): Changed to use

	* src/sh.ld: _reset should be adorned with CYG_LABEL_DEFN

	that CYG_LABEL_NAME was used, except for the scheduler lock which
	is special as it is defined in C as an asm alias.

	a macro which calculates the proper values based on baud rate
	and CPU clock speed.
