Re: [Tinycc-devel] Tdm-gcc (mingw) 4.8.1 win64 x86_64

[Christof]

Tried patch of grischka:
>tcc examples/fib.c
outputs fib.exe, however
>fib.exe
says "Invalid win32 program" + "access denied"

There is still something wrong with the generated pe-image.

For the moment I'll give up and stick to X86. 

Grischka: Thank's for trying to help.
