Summary: Avoid writting '\r' to files on MinGW

Initial Comment:
When using the "w" mode in fopen, MinGW translates LF into CR-LF. This creates havoc when reading the same file again, when sharing schematics files with other systems, and when placing them in a VCS.

This can be avoided by using the "wb" mode. The "b" is ignored on all POSIX conforming systems, according to these sources:

http://www.die.net/doc/linux/man/man3/fopen.3.html
http://www.opengroup.org/onlinepubs/009695399/functions/fopen.html

There are other ways, however. Adding 

#include <fcntl.h>
int _fmode = _O_BINARY;

on some source file should work as well. Another way is linking against the MinGW supplied binmode.o, which does exactly that.

Cesar
