Just change c_var() in scripts/qapi.py to have:

diff --git a/scripts/qapi.py b/scripts/qapi.py
index 8082af3..34bfbf6 100644
--- a/scripts/qapi.py
+++ b/scripts/qapi.py
@@ -131,6 +131,8 @@ def camel_case(name):
     return new_name
 
 def c_var(name):
+    if name in ['restrict']:
+        return 'q_restrict'
     return name.replace('-', '_').lstrip("*")
 
 def c_fun(name):

Then fixup and build failures (make sure to do a clean
first--dependencies seem to be off for qapi).
