I don't think you did anything wrong as this work on arm / Linux. I tried 
testing on x86 but got an assert failing at line 419 of x86_64-gen.c.

Might be x86 specific or windows specific. Unfortunetely, I don't have access 
a and the only x86 machines I have access to are quite remote from me which 
leads to terrible latency over ssh.

Could you first try with the current development code? Just clone the git 
repository with:

git clone git://repo.or.cz/tinycc.git

and then uses win32/build-tcc.bat to build tcc (as far as I know, I never 
compiled tcc for windows myself).
