Problem with linking samba with ncurses

[G2V WUch]

Hi,

I have problem with ncurses and building samba.

ncurses in samba is used by few binaries. One of these biaries is regedit.

On linkinking regedit it fails with

In other words it is issue with "cbreak" symbol however nm show this symbol in libtinfo

`cbreak` is used in samba code in https://gitlab.com/samba-team/samba/-/blob/master/source3/utils/regedit.c#L698 and to be honest I don't see anything special here.

As I'm working on the whole distribution there are no any other problems with ncurses DSos built out of source code configured like above.

Any suggestions what could be wrong in this case?🤔
