# splib is called by iplib.  For grib2, the iplib should be compiled in
# double precision, so that means splib should also be in double precision.
# (You could save time by rewritting iplib to call the single precision 
# version of splib.)
#
# To compile splib in double precision ${FTN_REAL8} with the options to
# set the compiler to use real*8 variables
#   gfortran:      FTN_REAL8="-fdefault-real-8 -fdefault-double-8"
#   ifort:         FTN_REAL8="-r8"
#
# problem with .mod can be on the default suffixes and invokes the modula2 compiler
