Liu, your messages do not reach the nano-devel mailing list.  Are you

But how then have you installed the ripped-out regex part from glibc?

Can you show us the full output of a bare ./configure run (without any
options) on your Windows machine?  Because the idea of gnulib is to allow
building on multiple platforms without any need for adjustments.  If that
isn't working, we need to fix it.

Is that web page valid for all BSDs?  Because I can find \< and \> for
FreeBSD and OpenBSD:

  https://docs.freebsd.org/info/regex/regex.info.The_Backslash_Character.html
  https://man.openbsd.org/regex

But NetBSD seems to know only [[:<:]] and [[:>:]]:

And it seems FreeBSD will lose the GNU extensions in the future:
