Otherwise the sources from a 'make dist' package wouldn't compile.

This change kinda got lost with the last commit re-splitting.

Autotools fix revisited.

.dirstamp, OTOH, is to be expected in several subdirectories.

 - no longer applicable: use autoreconf -fiv

A forgotten `#ifdef WIN32` broke UNIX build.

More MSVC adjustments, now focuses on the libvncserver

We also do not need the conversion between UNIX values to Windows values in the RTF_FIND_DATA struct, as we already are on windows.

The additional compat_mkdir function was not necessary at all.

`windows.h` is referring to `winsock.h` (unless the `WIN32_LEAN_AND_MEAN` is defined).
The structs used in this header are defined in `winsock2.h` or in `winsock.h`, but we are using Winsock2 of course!
So we have to include winsock2.h and refrain from including windows.h here

Basically taken from https://github.com/danielgindi/FileDir with some adjustments

Passing NULL to sprintf() would most likely crash the program.

`strings.h` and `resolv.h` are not available on MSVC, and some POSIX functions are renamed or deprecated

For all of those missing/deprecated POSIX functions, we just add a macro mapping to the _underscored version of MSVC.

The new x11vnc repo is at https://github.com/LibVNC/x11vnc.

This bug was introduced in the MSVC patches.

This topic branch provides compatibility for Windows, without the
MINGW32 dependency.

It is based on https://github.com/LibVNC/libvncserver/pull/22.

With Microsoft Visual C++, we cannot use pthreads (MinGW sports an
emulation library which is the reason we did not need Windows-specific
hacks earlier). Happily, it is very easy to provide Windows-specific
emulations for the pthread calls we use.
