PSPP-BUG: PSPP not compatible with Win XP anymore

[bugzillus]

OS: Windows XP SP3 32-bit

Installation of pspp-20181109-daily-32bits-setup.exe (1.2.0) and 
pspp-20200117-daily-32bits-ForTestingOnly-setup.exe (1.3.0 nightly) works, but 
running of the PSPP application is not possible:

0.10.2-g654fff seems to install and run properly.

1.2.0 fails on startup: "dwmapi.dll" not found

1.3.0 nightly fails on startup: "GetFileInformationByHandleEx" not found in 
kernel32.dll

In both cases, deinstallation via uninstall.exe fails: Deletion of files starts 
regularly with expected speed, then after a few seconds slows down extremely to 
like 1-4 files per second, while un_a.exe causes a steady CPU load of 25 %. 
After killing the uninstall task, deletion of the remaining 950 files with 
Windows Explorer completes within 3 seconds.

As dwmapi.dll was propably introduced with Vista and 
GetFileInformationByHandleEx might have been changed in Vista, I assume that 
the incompatibility might be related to changes in the Win platform SDK used 
for compiling, or some constant/value is used which is not supported on WXP, 
cf.

Thanks for looking into it. Cheers!
