Unthreaded NFFT needs the libwinpthread

[michaelquellmalz]

In Windows, when the NFFT is compiled without multicore support (OpenMP), the produced binaries still require the libwinpthread-1.dll to run. The only function they need from this dll is clock_gettime.

Any suggestion how we can fix that in our code?

The QueryPerformanceCounter (QPC) function looks promising and should be supported starting Windows 2000,
see MSDN: Acquiring high-resolution time stamps.

I tried to add a fix, but I'm unable to include the mingw windows.h in kernel/util/time.c

The main issue is that there is a conflicting typedef of the datatype INT:
Our infft.h defines typedef ptrdiff_t INT;
and inside windows.h (minwindef.h) there is the definition typedef int INT;

Currently, I have no idea how to fix this.

typedef ptrdiff_t NFFT_INT; + s/INT/NFFT_INT in the code base? Would probably require a soversion bump though.

Using such a generic name for the typedef was dangerous in the first place. People have been bitten by this before with libpng, libjpeg and many others legacy C-libraries. Unless there is a particular macro to be set before inclusion of the infamous windows.h to bypass the conflicting typedef, then I can't think of another option.
