Hello!

Was doing small test yesterday by changing a cpp file and compiling with
--debug=explain.  I realized that the explain argument did not print the
message I was expected on my centos build :

scons: rebuilding
`build/debug/sim/simulator/vr/pbs/fpsm/i86-pc-linux-gnu/pbsfpsm_acreport.o'
because:
           `sim/simulator/vr/pbs/fpsm/pbsfpsm_acreport.cpp' is no longer a
dependency
           `sim/simulator/vr/pbs/fpsm/pbsfpsm_acreport.cpp' is a new
dependency

I did some test on windows as well, by changing a cpp file too, and I got
this : 

scons: rebuilding
`build\debug\sr\sra\src\flatGui\win32\ASRResultObserverUI.obj' because
`sr\sra\src\flatGui\ASRResultObserverUI.cpp' changed

which is the message that I do expect.  So, I am wondering if it is the
message on centos makes sense. This message sounds like that the cpp is
being removed.  I double-check my pseudo-builder that creates Library and
Program, and the code executed is the same for both centos and windows.

I am using scons 2.5.1 with python 2.7.13

Thx
