Gettext-full: Fails to build -- gl_array_list.c

Hi folks!

I'm having trouble building gettext-full as a hostpkg.
I use the current HEAD of OpenWRT's github repo: 9519a62. My host system is Debian Testing (now Stable aka Bookworm).
Did anyone of you come across the same issue? Or does someone know how to fix this?

I already tried a make distclean.
make package/lib/gettext-full/hostpkg/compile V=s as well as make V=s return the following error:
