 Things to finish before moving onto compiler optimizations, C extensions, other nice features
 
-- self host. not yet compiling:
-    - c/eval.c, ir/fold.c (NYI flt -> u64 cvt)
+- self host -- working?? test thoroughly
+- fix preprocessor regressions though - e.g. <math.h>
 
 at some point add another backend like arm64 to make sure the non target specific stuff is generic enough..
