PPR does not compile with gcc

[smasson]

Context

There are multiple errors messages when compiling PPR with gcc

Error: Type mismatch in argument 'aa' at (1); passed REAL(16) to REAL(8)

Analysis

PPR uses the notation .d (for example 1.d0) to promote double precision.
As NEMO is compiled in double precision by default, this means that these ".d" variables are promoted to real*16.
All reals in PPR are declared as real*8 which creates the compilation error seen above.

Note that ifort does not complain when compiling PPR but I guess it is doing implicite real*8 <-> real*16 conversions...

Fix

replace all .d by a .e in all PPR/src files, for example with this small piece of shell :

for ff in ext/PPR/src/*90
do
   sed -e "s/\.d/.e/g" $ff > tmp
   mv tmp $ff
done
