** #NNN: dialects without support of single byte binary data
will now generate at least 2 bytes of storage for COMP-5 elements; this
applies to all non-standard dialects but GnuCOBOL (default) and Micro Focus;
that changes the group length of records containing elements with less than
3 digits and also passes different sizes via CALL, which may need program
adjustments.

** -std=acu / -std=acu-strict now generate BINARY and COMP-5 with at least
2 bytes of storage; the comment for #NNN above applies; if you want
to still use the sizes used since GnuCOBOL 2.2 with those dialects:
add -fbinary-size=1-2-4-8 to your compile options

* Important Bugfixes

** #904: MOVE PACKED-DECIMAL unsigned to signed led to bad sign
