[Wien] Latest WIEN2k compiled on different machines - different :ENE for TiC

Dear WIEN users,
I've installed the latest WIEN2k on two different machines :
* intel xeon + ifort 8.1 + mkl 7.0
* opteron + pgf90 5.2-4 + acml 2.0
To the best of my knowledge, compiler settings are as equivalent as possible.
For the TiC test case, I get total energies :ENE that differ by about 10^-4 Ry from one machine to the other.  (I compared the ifort+mkl to the precompiled executables on the xeon machine and found as good as identical results there.)
Has anyone compared these energies between different platforms and found agreement or disagreement?
And does anyone know what WIEN-version was used for the files in the TiC.tar testcase?
