Subject: base64: I/O should be performed in binary-mode
Date: Wed, 21 Apr 2010 18:46:23 +0900

base64 doesn't call freopen() nor setmode() against stdin, and doesn't
give "rb" flag to fopen(). So, base64 sometimes fails to encode data
correctly on some environment. For example, zsh on Cygwin forces stdin
to be text-mode.

Test case (zsh on Cygwin, filesystems are mounted as binary-mode):
$ printf '\x0D\x0A' > crlf-src
$ base64 < crlf-src | base64 -d > crlf-dst
$ cmp crlf-src crlf-dst
crlf-src crlf-dst differ: char 1, line 1
