This change adds a configure test to see if localtime_r
exits, and only enables the QEMU impl if missing. We also
re-arrange qemu-common.h try attempt to guarantee that all
source files get unistd.h before time.h and thus see the
localtime_r/gmtime_r defs.
These are only with --enable-werror, right? The patch shouldn't be
necessary for 2.4.

It isn't necessary for 2.4. There are more severe problems which also
seem to be triggered by recent changes in the MinGW-w64 toolchain:
64 bit executables crash at longjmp from generated code,
and networking fails because of asynchronous connect calls
which were never implemented correctly in the slirp code.
I'll try to summarize all that I know in a separate mail later.
I only recently got reports about these problems and think
that it is too late to fix them in 2.4.0.
