[ECOS] Re: Typo in assert error message causing confusion?

I get your point of view. However, I assume that someone would like to know
what's broken instead of what would be the case if the message would have
not been displayed. If my system stops with a kernel panic and tells me
"Pointer is valid" I would be like -> oO.

As I can see inside eCos source, I'm not the only one understanding those
assertion messages this way, some examples:
CYG_ASSERT( freeret , "Couldn't free!" );
CYG_ASSERT( interr == 0, "internal lock failed!" );
CYG_ASSERT( usertmp->next != NULL, "Couldn't find message queue user" );
CYG_ASSERT( stacksize >= PTHREAD_STACK_MIN, "Inadequate stack size
CYG_ASSERT( ticks != 0, "Zero tick count");

To sum it up:
- Some eCos developers use assertion messages to say what failed
- Some eCos developers use assertion messages to say what would have passed
This inconsistency confuses people like me, new to eCos and debugging
something which I don't fully understand yet.

Any further comments/opinions?
