Compile warnings while installing

[jcs090218]

I am getting these warnings during the installation. 😕

In end of data:
snippets/bibtex-mode/.yas-setup.el:4:1:Warning: the function
    `yasnippet-snippets--no-indent' is not known to be defined.

In end of data:
snippets/python-mode/.yas-setup.el:39:1:Warning: the function
    `yasnippet-snippets--fixed-indent' is not known to be defined.

Uhm I guess the function is not available at compile time but it's not actually an issue since it works at run-time.
Not sure how to hide the warning, any idea @npostavs maybe?

I think (require 'yasnippet-snippets) in the .yas-setup.el files would do it.
