Subject: ncurses 6.1 - patch 20180609
X-Git-Tag: v6.2~85
X-Git-Url: https://ncurses.scripts.mit.edu/?p=ncurses.git;a=commitdiff_plain;h=e23d7db3de8b85766c7c1ccf66b738870b473da2

ncurses 6.1 - patch 20180609

+ modify generatesd ncurses*config and ncurses.pc, ncursesw.pc, etc.,
  to list helper libraries such as gpm for static linking (Debian
  #900839).
+ marked vwprintw and vwscanw as deprecated; recommend using vw_printw
  and vw_scanw, respectively.
