Agree that this wouldn't be too hard to implement, but should be done on the dev branch.

Hope the new description is correct. Please feel free to change it if it isn't to the point.

I also lowered the priority for this feature request since the workaround is easy: configure with "--enable-link-all-dependencies".

I think it would be fine to look into making the default value of --enable-link-all-dependencies vary depending on the detected build system. Ok to retitle this as such and call it a feature request, and include the macOS preference as well? This would be better worked on and tested on the default branch for Octave 6.

As reported in bug #53627, Octave fails to compile with default parameters on cygwin with the following linking error:

config.status: executing liboctave/mk-version-h.sh commands
CXXLD libinterp/dldfcn/__delaunayn__.la
libinterp/dldfcn/.libs/libinterp_dldfcn___delaunayn___la-__delaunayn__.o: In function `free_qhull_memory':
/pub/devel/octave/hg/octave-build/../octave/libinterp/dldfcn/__delaunayn__.cc:84: undefined reference to `warning(char const*, ...)'

Linking reportedly succeeds if configure is run with the "--enable-link-all-dependencies" option.

Should this option be enabled by default on cygwin (and possibly other platforms requiring "-no-undefined")?
