[Spice-devel] [PATCH 13/15] common: don't try to redefine PANIC if it already exists

[Christophe Fergeau]

canvas_base.c tries to define PANIC, but it might already be set
if eg client/debug.h has been included before. All the other
macros in this file are guarded by #ifndef, this commit adds
the missing #ifndef to PANIC. Note that this is just a bandaid,
ideally common/ would contain a logging frameword, and these
macros would only be defined once instead of being defined in
several places.
