— Make style consistent between ObjFW and ObjFW_RT
ObjFW_RT used to be a separate project that followed the BSD style, as
it was written in pure C, while ObjFW's style is based on the BSD style
with changes to make it a better fit for Objective-C. This commit
changes ObjFW_RT to use the same style as ObjFW. (user: js, size: 4282) [annotate] [blame] [check-ins using]
