Description: Problems compiling share code (shr_scam_mod.F90) with intel compilers

Information:

Several users in the community have reported compilation hangs or extremely
long compile times for the file shr_scam_mod.F90 in the csm_share build
with various intel compilers.

We believe this is a compiler problem.  A short term fix is to edit
models/csm_share/shr/shr_scam_mod.F90 as follows; comment out any lines
associated with declaration or use of the variable SDAT.  This code is
only needed when running with the data ocean model in scam (single point)
mode.  Most users are probably not doing that.  Adding a shr_sys_abort
call in the appropriate location will confirm that the code is not needed
at run time.  

The changes in models/csm_share/shr/shr_scam_mod.F90 should look something like

line 280:
! type(shr_strdata_type) :: SDAT

line 349+:
call shr_sys_abort('shr_scam_checkSurface abort for SDAT')
! call shr_strdata_readnml(SDAT,ocn_in)
! call shr_dmodel_readgrid(SDAT%grid,SDAT%gsmap,SDAT%nxg, SDAT%nyg, &
! SDAT%domainfile, ocn_compid, ocn_mpicom, '1d', readfrac=.true., &
! scmmode=.true.,scmlon=scmlon,scmlat=scmlat)
! nfrac = mct_aVect_indexRA(SDAT%grid%data,'frac')
! if ( present(ocn_present)) ocn_present=(SDAT%grid%data%rAttr(nfrac,1).gt.0.)
! if ( present(ocn_present).and.present(ice_present)) ice_present=ocn_present
! if ( present(lnd_present)) lnd_present=(SDAT%grid%data%rAttr(nfrac,1).lt.1.)
