[Nobug] NoBug inconsistency or feature

[benny.lyons at uniserv.com]

Hi, 
While playing around with NoBug, I came across something that caused me
a few heartaches until I got to the bottom of the matter.

I've got a makefile with 3 different targets corresponding to the 3
different
NoBug build-levels: alpha, beta and release. Each target has its own -D
flag, specifying either EBUG_ALPHA, ...

Now I had a #define somewhere in one of my source files: something like
#define EBUG_BETA

Building with targets release caused a compiler error...that's good, but
building target ALPHA, didn't do anything (I think building target BETA
caused
a warning)!    

If you got the build level defined to two different levels, I think it
would be 
better if the compiler came back with an error instead of the current
tolerant usage
where one of the debugging levels wins and the user is left with a
surprise as
to which debugging level results.  The user can then go and figure out
which build 
level is actually  preferred.

I've locally fixed this in nobug.h with something like:
#ifdef EBUG_ALPHA
#ifdef EBUG_BETA
#error Some error message
#endif
#endif

Is this bad or is there some purpose to having tolerant behaviour?
