* gcc-interface/decl.c (gnat_to_gnu_field): Post the error message
for parent overlapping on the position instead of on the first bit.
For a field that needs strict alignment, issue the error for the
position first and, for the size, issue an error if it is too large
only for the atomic and aliased cases. Issue a specific error if
the size is not a multiple of a byte in the volatile and the stric
alignment cases.
