Re: Cygwin x86_64 support for GCC 4.8.x

Hi Kai,

I see. My apologies, I'm not familiar with the GCC merging policy.

In any case, where does GCC document the list of supported
target/host/build configurations?

I was trying to build GCC 4.8.1 with following configuration: HOST &
BUILD: Cygwin 64bit, TARGET=arm-none-eabi

I ended up with successful build/install that generated runtime errors
which I had to investigate (while same on Cygwin 32 was fine).
So it shall be either documented that such configuration is not
supported or (better) it shall generate a warning/error at configure stage.
