Could you elaborate more about this (i.e. show where mixins is 
more readable, debugable and less stressful to the compiler)  ? 
This kind of information is good for tuning stage later. My goal 
now is to finish the conversion and running of the header and the 
test code 
(https://github.com/attractivechaos/klib/blob/master/test/khash_test.c).

I noticed the -E option recently but haven't really used it. I 
now generated the pre-processed source and try to make use of it.
