Results different for rain_ice_old

[SebastienRietteMTO]

On a small 3D case with AROME (small_2D_alt9), the results given by rain_ice_old are different between commits 37885e5 and 6e28495.
It could be due to the merging of branch 'rain_ice_old' of https://github.com/rolfhm/PHYEX or due to the branch itself.
Investigation and/or bug correction needed.

Commit 8956c54 solves an issue about real*4/real*8
Commit 2116737 solves two issues introduced in the rolfhm-rain_ice_old branch
The last commit compatible with 48T3 (9164c67) once patched (leading to commit bd44ba7) reproduce correctly the results obtained with the reference version for the small_3D_alt9 case in 48T3 (obtained by commit d10ed48).

Commit 110a5aa (obtained by application of the patch on the master branch running on CY49T0) doesn't reproduce the small_3D_alt9 case results obtained with the original CY49T0.
Is there a bugfix in PHYEX that is not included in CY49T0?
Is there an issue introduced in PHYEX when changing the reference from CY48T3 to CY49T0?

[SebastienRietteMTO]

The results from commit d10ed48 was not equal to the results from the original CY48T3 either.
It could be the reason why commit 110a5aa does not reproduce the original CY49T0.
