Martin Storsjö c0bd865ad6 configure: Add -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600 for mingw as well 
Mingw headers have got header inline implementations of localtime_r
and gmtime_r, but only visible if certain posix thread safe functions
have been requested.

This is a preparatory step for improving the detection of those
functions.
