* src/mat5.c (ReadNextCell): Move code calculating number of cell array
      elements and common initialization of data size, number of bytes, and
      data out of conditional for compression

* src/mat5.c (ReadNextCell): Move err variable declaration into compression
      condition scope where it is used

* src/mat5.c (ReadNextStructField): Move code calculating number of elements
      in the struct out of compression condition

* src/mat5.c (ReadNextStructField): Move err variable declaration into
