Module Name: src
Committed By: martin
Date: Sun Jul 28 10:21:18 UTC 2019
Modified Files:
src/distrib/utils/libhack: Makefile.inc multibyte.c
Added Files:
src/distrib/utils/libhack: nl_langinfo.c strcasecmp.c
Log Message:
We (especially libcurses and nvi) use more multibyte character locale
related symbols nowadays. Update libhack to avoid pulling in full grown
multibyte locale support on small install media.
