Thanks for the prompt reply (to Nick n_ecos@targus.net, not me)
However, your fix did not change anything -- error exactly
as before:

+volatile cyg_int32 dsr_disable_counter  // DSR disable counter
+               CYGBLD_ATTRIB_ASM_ALIAS( cyg_scheduler_sched_lock );

PRODUCES:
	undefined reference to 'dsr_disable_counter'

Can you tell me what, if anything, would be wrong with doing
it the following way?

volatile cyg_int32 cyg_scheduler_sched_lock;
#define dsr_disable_counter cyg_scheduler_sched_lock  // DSR disable counter

First of all, it isn't clear to me that this is where the storage for
cyg_scheduler_sched_lock is supposed to be defined.  Also,
the dsr_disable_counter alias is limited to this file. Does
dsr_disable_counter need to be a global alias?  I can't find any
other references to it.

Do you have any idea why I would be having this problem with
gcc version 2.95.1 19990816 (release) under Redhat 7.0? I assume
this links correctly in your environment(which is what?).
I can't use the next version of GCC because we are cross-compiling
for the Hitachi SH (which apparently broke in 2.95.2),
could this be a compiler bug?

           - Peter
