Subject: Fix (again) problems displaying a GtkSourceView widget on Cygwin
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ab6a775adf51dff998699ed87904d9436e65ce9a;hp=00fd47eccf62f5657bc32655bdddcf3758d882e2;p=pspp

Fix (again) problems displaying a GtkSourceView widget on Cygwin

Under certain compiler options, the effect of the gtk_*get_type
function call was optimised away.  This change fixes that.  It
seems that both static and volatile are necessary, in order to
avoid the compiler from complaining and/or optimising the call
away.
