[lttng-dev] [Babeltrace PATCH 08/23] Add MinGW implementation of gmtime_r

[Ikaheimonen, JP]

Add a (non-recursive) implementation of gmtime_r, as it missing
in the MinGW library.
Implementation is written in file include/babeltrace/compat/time.h
which must be included in the source files that call gmtime_r.

Note that the Windows function gmtime_s is not available under
MinGW32.
