Compiling on Win 7 (32 bit) fails

[dgollub]

Hi,

I am trying to compile promptoglyph on Win 7 (32 bit) with this D compiler version:

dkg@x60s-dkg:~/whome/Projekte/oss/promptoglyph$ dmd --version
DMD32 D Compiler v2.067.1

And this is the result:

dkg@x60s-dkg:~/whome/Projekte/oss/promptoglyph$ make clean
rm -rf build promptoglyph.tar.gz
dkg@x60s-dkg:~/whome/Projekte/oss/promptoglyph$ make
dmd -wi -g -debug -ofbuild/promptoglyph-path promptoglyph-path.d help.d

I have not checked the source yet, because I have no time right now. As soon as I have some more time I will have a closer look, but no promises :-)

The issue is that I'm using Posix poll to allow the prompt to exit early if git status blocks for longer than we want. From the code:

// Currently we can only do this for Unix.
// Windows async pipe I/O (they call it "overlapped" I/O)
// is more... involved.
// TODO: Either write a Windows implementation or suck it up
//       and do things synchronously in Windows.

On Posix, I can just poll a file descriptor, but continue using the D standard library for everything else. On Windows the situation is a bit more complicated. I have to use the Windows API for reading the file instead of the D standard library (since the needed OVERLAPPED struct gets passed into their ReadFile call). I'd certainly like to support Windows. It's just something I didn't get around to yet since I spend most of my time (whenever I'm not gaming) on Linux.
