Because recent MSVC's(2013 and never) supports native longdouble i think we should remove that emulation away.

VS knows "long double", but it is not 80 bits wide, but just the same 64 bits as "double".

Let's not break VS2010 compatibility please.

@Andrej for which purpose we should keep it ? Maybe be should have compatibility for vs 2005 too ? I think we should go forward.

But ok i googled and yes long double in VS is alias of double. Too sad.

DMD is supported on systems from Win7 onward (XP also works but Walter decided it should become deprecated). VS2013 requires Win7 SP1 at a minimum.

VS2013 supports Windows XP targeting with v120_xp toolset.
It must be deprecated. Windows XP is the past. Its lifetime already ended.

Do you have a link to where Walter said this?

Excluding Windows 7, XP still has a bigger desktop market share than all other operating systems combined, according to some sources.  Age is not a good reason D shouldn't support the second most common operating system.

We shouldn't force anyone to upgrade their toolchain without a very good reason either.

The way I see it, if it's not /too much/ trouble then there's absolutely no reason to break tools.

Recently and somewhat related: someone reported to Epic that UE4 didn't work on XP. They responded promptly that they're going to fix the issue ASAP. Business is business!
