Subject: gui: Create user settings directory if it doesn't already exist.
X-Git-Tag: sav-api~195
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=pspp;a=commitdiff_plain;h=22f5cb71af029deb1c919b7c6bc958572f8da9f9

gui: Create user settings directory if it doesn't already exist.

The user settings directory doesn't necessarily exist.  Some program has to
create it, and PSPPIRE might be the first program that wants it, so it
should try to create it.

Discovered on OpenBSD.
