Preprocessor problem when compiling branch 4.2

I see that in all arch .fcm files the fortran compiler (I am using IntelOne compiler suite) is invoked with the -cpp key, does this mean that running a preprocessor separately is not tested/working?

I am using this 2431247b commit with the additions for compilation on our infrastructure.

I am having problems even if I add the -cpp key to the compiler command when processing the following:

initial fortran code (in the included .h90 file)

SUBROUTINE lbc_nfd_/**/PRECISION( ptab, cd_nat, psgn, khls, kfld )
TYPE(PTR_4d_/**/PRECISION),  DIMENSION(:), INTENT(inout) ::   ptab        ! pointer of arrays on which apply the b.c. 
...

code in ppsrc

SUBROUTINE lbc_nfd_/**/sp( ptab, cd_nat, psgn, khls, kfld )                                                                                                                                                                      
TYPE(PTR_4d_/**/sp),  DIMENSION(:), INTENT(inout) ::   ptab        ! pointer of arrays on which apply the b.c.
...

The token /**/ is replaced by a space and the compiler complains.
