I've been having the same problem as you, though YCM compiles fine under 32-
bit Cygwin. I don't think that using the i686 compilers is the way to go 
because, as said at the top of this page (https://github.com/Valloric/
YouCompleteMe/wiki/Windows-Installation-Guide):

"Before starting this installation procedure, it's critically important 
that you understand that the architecture (x86 vs x86-64) that you build 
ycm_core.pyd for has to match the architecture of the python27.dll on your 
system and the architecture of the Vim binary you will be running. All 
three need to match, otherwise things won't work."

I have also tried downloading older versions of YCM, up to August 2013, 
because that's when the author of the YCM installation for Cygwin guide 
(see link above) wrote his guide. Still the same LONG_INT error.

I hope a solution for this emerges.
