Note that on MingW, `stdin` and `stdout` are not opened in binary mode by
default, this means `Nyaruko` may not faithfully encode files on MingW.
default, this means `Nyaruko` may not faithfully reproduce files on MingW.
As a workaround, a `binmode_main.h` is included, so it's possible to produce
an encoder that's binary-clean like this:
``` <!---sh-->
x86_64-w64-mingw32-gcc -include binmode_main.h nyaruko.c -o nyaruko.exe
```
The C code produced by the encoder will need to be compiled with the same
`-include binmode_main.h` hack if you want its output to faithfully reproduce
the original binary input.

/* Preprocessor hack to set binary mode for stdin and stdout.
This replaces main() with an alternative function forces binary
modes. This is intended to included via compiler arguments, so we
would be able to enable binary modes without modifying the original
program source. Conceptually, it's similar to LD_PRELOAD, except
we hack it in via preprocessor.
It only works for programs where main() occurs just once.
