C_MATCH_HISTORIC_TAL
Example 9-19 on page 9-41 shows the C source generated for the given DDL source
with C_MATCH_HISTORIC_TAL in effect which allows substructures to start and end
on odd-byte boundaries. If the C_MATCH_HISTORIC_TAL command is not in effect, C
source will not be generated for def f because substructure j starts on an odd-byte
boundary. The DDL compiler emits a filler at level 2 after k because the following data
items will not fit in the remaining byte.
