5.1.1 binaries wont load on WinXP

[bulk88]

VC 2012 SP0 (?, but not SP1, google it) dropped WinXP support. 5.1.1 gives a "is not a valid win32 application" popup on WinXP. This specifically is because of " 6.00 operating system version" in the PE header of the binary. Going backwards through the sourceforge releases, 5.0.1 is the newest version I could run on WinXP. Could you please restore WinXP support in your distributed binaries?

I wasn't aware of this issue. I have a clean XP virtual machine for testing, but I guess I haven't tested since I upgraded the compiler. I'll make sure 5.1.2 works on XP if I can. Sounds like it's just a question of getting SP1. I hope to get 5.1.2 out soon.
