Warning about misaligned elements in structure

The 16.0 compiler issues the following warning message about a structure:

..\include\dmumps_struc.h(14): warning #6379: The structure contains one or more misaligned fields.   [DMUMPS_STRUC]
      TYPE DMUMPS_STRUC

Although I wish to make this message go away, by inserting padding or rearranging the sequence, in this case the declaration of the structure (i.e., user-defined type) spans 265 lines, causing the number of suspects to be large.

It would help if the compiler flagged (or flagged when requested) the particular structure members that caused the misalignment.
