Subject: Fix bug reported by Jason Stover.
X-Git-Tag: v0.6.0~323
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e5d44b86ac3697290369f39ea2905f9cc27345e4;p=pspp-builds.git

Fix bug reported by Jason Stover.
* settings.c: Move get_termcap_viewport and in particular the
#include for <curses.h> to the end of the file.  curses.h
redefines bool on some systems (e.g. OpenBSD), which causes
disagreement between uses of bool before its inclusion and
afterward.
Tested by Jason Stover.
