Intermediate files and multiple target rules

[Andriy Sen]

Hello,

I have found inconsistent behavior of make in regard to chain of implicit 
rules with multiple targets.
For example lets suppose we have a rule that generated multiple c++ files:

%1.cpp %2.cpp: %.ext
   [command]

The c++ files are subsequently compiled and linked. GNU make is treating the 
file that triggered the above rule as intermediate and removes it at the end 
but leaves the other one alone.
The version of make I'm using is 3.81.

Thanks,
Andriy
