Make the modifications necessary to compile dump1090 for WinXP, Win7 and hopefully Win8. The files can be compiled using M$ Visual Studio/C++ 6.0. Due to various licensing issues, I haven't included the libraries or DLLs. You will need to locate pthreadVC2.lib and rtlsdr.lib to link the file, install the zadig drivers to support the dongle, and locate libusb-1.0.dll, msvcr100.dll, pthreadVC2.dll and rtlsdr.dll. dump1090.exe will not run on any Windows version prior to XP SP2, because msvcr100.dll imports several functions from the Windows kernel that are not available on earlier versions. This means dump1090 won't work on Win2K. The major change to the code relates to file handles. The original code assumes Linux behaviour in that handles are allocated from 0 sequentially upwards. However Windows handles are allocated pseudo randomly, and handle numbers greater than 1024 would break the code. The code has therefore been modified to use a linked list of connection structures, rather than a static array limited to 1024 entries.
