+// !!! For a structure with a series of bit fields and used as a storage in vfr file, and if the bit fields do not add up to the size of the defined type.
+// In the C code use sizeof() to get the size the strucure, the results may vary form the compiler(VS,GCC...).
+// But the size of the storage calculated by VfrCompiler is fixed (calculate with alignment).
+// To avoid above case, we need to make the total bit width in the structure aligned with the size of the defined type for these bit fields. We can:
+// 1. Add bit field (with/without name) with remianing with for padding.
+// 2. Add unnamed bit field with 0 for padding, the amount of padding is determined by the alignment characteristics of the members of the structure.
