get _DEFAULT_SOURCE special case (report by Adam Sampson)
- Port patch ncurses-6.3.dif

- Add ncurses patch 20220924
+ modify configure macro CF_BUILD_CC to check if the build-compiler
works, rather than that it is different from the cross-compiler, e.g.,
to accommodate a compiler which can be used for either purpose with
different flags (report by Mikhail Korolev).
+ fix another memory-leak in tic.
+ correct change for cppcheck in menu library (report/analysis by
"tuxway", cf: 20220903).

* ncurses-6.3.dif

- Add ncurses patch 20220917
+ reduce memory-leak in tic by separating allocations for struct entry
from TERMTYPE2 (cf: 20220430).
+ improve interaction between tic -v option and NCURSES_TRACE, by
processing the latter only when -v option does not set _nc_tracing.
+ modify curses_trace() to show the trace-mask as symbols, e.g.,
TRACE_ORDINARY, DEBUG_LEVEL(3).
