digitalmars.D.learn - Which GDC to download?

Windows X86 64bit (x86_64-w64-mingw32)

Standard builds
Target			DMDFE		Runtime	GCC	GDC revision	Build Date
arm-linux-gnueabi	2.066.1	yes	5.2.0		dadb5a3784	2015-08-30
arm-linux-gnueabihf	2.066.1	yes	5.2.0		dadb5a3784	2015-08-30
x86_64-w64-mingw32	2.066.1	yes	5.2.0		dadb5a3784	2015-08-30

I'm totally confused about what does these mean:

1) Why there is a download targeting arm-linux-gnueabi(hf) and 
what exactly it means? Is this a cross-compiler which will 
produce obj files containing ARM instructions or what? If so, 
will linking just work? and how?

2) Is what I understand from "cross-compiler" correct? (a 
compiler that can target different architectures than the host 
architecture it's compiled for)

3) Which one to choose if I just want to write & compile windows 
programs?

4) x86_64-w64-mingw32 is commented as "Unsupported alpha build. 
SEH"? is that means windows-targeting version of the compiler is 
highly unstable/not ready yet? What's "SEH"?

Yes, that's a cross compiler. You run it on Windows to produce 
programs for an ARM device running Linux (for example, you do 
your development on Windows but want the program to run on a 
Raspberry Pi)


 3) Which one to choose if I just want to write & compile 
 windows programs?


The x86_64-w64-mingw32 one. That means Intel processor, Windows 
64 bit. mingw32 is the library used by gcc to make Windows 
programs.

You could also use the 32 bit one below, i686-w64-mingw32, both 
should work on Windows.

SEH is Windows' "Structured Exception Handling". The open source 
compilers (not just D, basically all of them) historically 
haven't done a great job implementing that but have recently been 
fixing their problems.

You'll probably be fine using it though.

Linking only works for libraries which are included with the cross
compiler. That usually means only the C/C++/D standard libraries will
be available. You can link to other libraries with a cross-compiler, but
you need to provides these libraries in some way:

Adding to Adams answer I guess we (the GDC team) have to somehow
present 'native compilers' more prominently.

Unfortunately Windows GDC builds are very unstable right now. I'd
recommend using DMD or LDC for Windows.

Well... To me it's surprising GDC is not usable on windows but I 
doubt LDC is more stable.  Sad...
