will be blown away by PCH, it must be temporarily copied to
|

malloced memory. (The macros will refer to identifier nodes which

before the PCH file is loaded, so it doesn't matter that this is

a little expensive.

It would reduce the cost even further if macros defined in the PCH

for builtins, and for #assert by default. */
