Thanks, I wondered if it had been posted, as it's the kind of 
oddity they might enjoy. :)

It's not hard to figure out, as 'git apply ldc_android_arm' says 
it fails on dmd2/root/port.c and 'git log dmd2/root/port.c' shows 
this recent change to master:

https://github.com/ldc-developers/ldc/commit/556e3a691f72b97cce31d85740e8dc12cafc9f53#diff-2268700876655bdfa9d178b9cc466277

I've updated the gist and wiki page to take that change into 
account; simply download the new gist, as shown on a reloaded 
wiki page.

Also, I haven't tried cross-compiling from Windows, so you may 
run into other problems there.  The main one I can think of is 
that the test runner targets I added to CMake may have an issue, 
but there could be additional incompatibilities that I simply 
haven't run into on linux.  Hopefully, it just works. :)

Anyway, this is a good reason to get all this stuff merged soon, 
which is what I was looking into now anyway, although that 
particular change is from Kai's long-unmerged longdouble2 branch.
