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.
