[groff] 17/34: Drop support for `ARRAY_DELETE_NEEDS_SIZE`.

[G. Branden Robinson]

gbranden pushed a commit to branch master
in repository groff.

commit bda851ae93e1979514b547e0e83992092719ab64
Author: G. Branden Robinson <g.branden.robinson@gmail.com>
AuthorDate: Sat Aug 28 09:45:16 2021 +1000

    Drop support for `ARRAY_DELETE_NEEDS_SIZE`.
    
    * src/include/lib.h [ARRAY_DELETE_NEEDS_SIZE]: Drop preprocessor
      conditional branch.  This abandons support for certain pre-ISO C++98
      compilers.  (According to a now-removed comment, unsized array
      deletion was documented in "ARM", meaning _The C++ Annotated Reference
      Manual_, published in 1989.)
    
    * Makefile.am: Undocument preprocessor symbol.
