Does anything happen if it's not equal? Or is there an implication that 
something somewhere else won't happen if the IF-test fails because the enclosed 
statements didn't run?

I can _imagine_ someone from years gone by using something like this as a part 
of code that was generated so that under different circumstance a different 
source line would have been auto-gen'd into the code to result in a value other 
than 123, perhaps because the referenced numeric field might sometimes be 
signed and otherwise unsigned.

Or perhaps the 'ABC' constant would be used as a marker in the compiled object 
in order to recognize a reverse-engineered kind of rip-off? A few of these 
sprinkled around weren't unheard of and I believe still are used. It might just 
be a remnant that never got cleaned up.
