Hello, when analyzing the output from `h5fc -show', which e.g. on my Linux system is gfortran -I/usr/include -L/usr/lib64 -lhdf5hl_fortran -lhdf5_hl -lhdf5_fortran -lhdf5 one would like to put all options of type -Ldirectory into variable HDF5_FLIBS (for the linking flags) instead of HDF5_FFLAGS (for the compilation flags). The attached trivial & obvious patch fixes this. Feel free to use it. Thanks, Harald
