Hi!

MSVC can't generate precompiled headers on a network drive so I used Copy
factory to copy necessary files somewhere to c:\temp. This causes a strange
behavior after fresh checkout when there is no .sconsign.dblite file. If I run
the scons twice then the second run should do nothing but it recompiles all
again because of changed dependency order of the precompiled header object.
Third run is fine. This happens only if the copy target is an absolute path out
of the source tree.

Can you attach the output from:
scons --debug=explain
scons --tree=prune
