Hi Eric,

Now that the header and licensing of compiler.h got amended, can we look at 
this again?

I think the right solution (at least for the moment) is to stick with my series 
to fix the build.
1/2) We get the ignore_value() macro in.
2/2) We ignore the return value of that fwrite().

As I clarified on my last e-mail in this thread (21/sept), there are many other 
calls around the replay code which could potentially fail and are all 
unchecked. We could at least fix the build now and then talk about a separate 
series to address those, if neccesary.
