On Windows \n is CRLF, not LF, even in C. This can cause problems when reading and writing files that shold be binary but are written as text and vice versa.

Update: as ikegami correctly points out, I was conflating the disk version with the in memory version of these strings. \n should always be the line feed (in memory) and the I/O subsystem should have converted it.
