Adjusted alternate version to preserve formatting
The first alt version added some whitespaces that broke the outline, so I simply filled those up. I also expanded tabs to spaces since there is no size limit restriction for the alternate version. The second alt version attempted to force binary mode with _setmode() and _fileno() calls, plus some additional headers. Rather than doing it this way, I hack in the binary mode adjustments via preprocessor. Actually I did a similar trick for IOCCC 2011, but I guess I didn't submit that version: https://uguu.org/archive/ioccc2011/akari/source/binmode_main.h The file above uses _setmode() and _fileno(). The leading underscore indicates that they were nonstandard extensions. For the binmode_main.h in this change, I have opted for setmode() and STDIN_FILENO instead, which are more widely available.

/* 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.
