remove warnings by reordering headers

[eddelbuettel]

This covers only one of the two files emitting a fair amount of warnings. I'll try to get to the other one too.

It is driving me a little batty that I cannot get of the warnings when compiling src/bigmemory.cpp. Hm.

Many thanks!

[eddelbuettel]

Oh, you were too fast. I figured it out and wanted to expand the PR but somehow it did not let me -- so just sent you a new one.

[kaneplusplus]

OK, sounds good.

[eddelbuettel]

Is this ok / expected or an issue: https://travis-ci.org/kaneplusplus/bigmemory/builds/86677806 ?

[kaneplusplus]

I think it's a coveralls issue. I usually hit restart the build until it works or gives a more definitive error related to the packages.

[eddelbuettel]

I may be blind but I do not see the 'retickle this' button...

[kaneplusplus]

It's on the right under settings. I've restarted.

[eddelbuettel]

I looked, I only see 'requests' -- may be different for you as "owner".

[kaneplusplus]

That's probably right. Thanks again, I've merged the second pull request. It's building without problems on Linux and I built it on my Mac. This was extremely helpful.

[eddelbuettel]

My pleasure -- I much prefer clean builds too :)
