The previous code made incorrect assumptions about Qt6's file hierarchy. Reuse automatic configuration (with pkg-config) for Qt5, and replace '5' by '6'.
Also fix a typo in multiw-2.370.
If using hints file sys/unix/hints/linux.370 or sys/unix/hints/macOS.370
allow the majority of the boilerplate compile switches to reside in a
compiler response file, instead of on the command line.
Include one of the following on your make command line:
make response=1
or
make resp=1
It can be combined with other make command line options. See
sys/unix/README-hints for further information about those.
The response files that it uses are:
CC (clang or gcc) src/nethack_cc.rsp
CXx (clang++ or g++) src/nethack_cxx.rsp
Note: I think the reduced clutter should actually become the default,
and the override should be noresponse=1 to NOT use it, but I'm
not sure how others feel, so for now, it requires
make resp=1
Feedback on whether that should become the default or not
is welcome.
Tested on Linux with gcc-15 and on Linux with clang-20.
I haven't had a chance to test it on macOS yet.
OpenSUSE Tumbleweed ncurses 6.5 requires the one in
/usr/include/ncursesw/curses.h, if ncursesw is being used.
Otherwise, several needed function prototypes are not there.
Fixes#1427
There are warnings within the qt6 header files if c++20 is not used, for example:
usr/include/x86_64-linux-gnu/qt6/QtCore/qfuturesynchronizer.h:21:5: warning: use of the 'nodiscard' attribute is a C++20 extension [-Wc++20-attribute-extensions]
21 | Q_NODISCARD_CTOR_X("Use future.waitForFinished() instead.")

QMake version 3.1
Using Qt version 6.8.3 in /usr/lib/x86_64-linux-gnu
GCC15 switched its default to -std=gnu23 and there's a bug in
pdcursesmod as a result. That impacts MSYS2/Mingw64 NetHack builds.
See: https://github.com/Bill-Gray/PDCursesMod/issues/333
The suggestion there is to force --std=gnu17 as a workaround.
