 for some tips on fixing various errors you may encounter, including
 this one. (I opened that issue like 8 months ago...)

I followed your reported issue. I could fix first 2 points but I get
different error after that.

(cd src/libmath; mk  all)

I tried to find sizeof in mathi.h but I can't really find
anything. (Yeah there is no sizeof in
either mathi.h or related
files). 

I'm unsure what the error is indicating. Any idea on how to proceed further?.
