In a nutshell, Emacs 24.3.93.1 produces:

--8<---------------cut here---------------start------------->8---
(define-package "yasnippet" "20140821.38" "Yet another snippet extension for 
Emacs." 'nil :url "http://github.com/capitaomorte/yasnippet"; :keywords 
("convenience" "emulation"))
--8<---------------cut here---------------end--------------->8---

instead of:

--8<---------------cut here---------------start------------->8---
(define-package "yasnippet" "20140821.38" "Yet another snippet extension for 
Emacs." 'nil :url "http://github.com/capitaomorte/yasnippet"; :keywords 
'("convenience" "emulation"))
--8<---------------cut here---------------end--------------->8---

For a reason which still escapes me, only Cygwin Emacs bugs because
"convenience" is not a function.

w32 binaries don't say anything, and load the packages properly!?
