The attached patch adds fallback implementations for localtime_r and
gmtime_r that should work properly on MINGW and other targets where we
support OpenMP and that have threadsafe localtime and gmtime.

Ok for trunk?

PING!

Additionally, to be really sure I have also tested the fallback implementations on Linux. So, this patch ought to

1) Fix the PR on targets that have the _r functions.

2) Fix the PR on targets without the _r functions, but with threadsafe localtime(), gmtime() (MINGW, maybe others?).

3) Doesn't regress on other targets.

4) Does not fix the PR on targets where we support OpenMP, but do not have either the _r functions nor threadsafe localtime/gmtime, if such targets indeed exist at all.
