Hello Elie,

I did manage to build Calypso on Win7, and the resulting binary 
works to produce an obj file, but linking of a full executable 
fails :(

I am getting "file contains invalid .pdata contributions" when 
trying to link. Trass3r over on ldc's github page was getting 
this error at one point also, but I don't know what the solution 
was. It seems like this was back in Aug 2014 so I would have 
thought any changes needed were picked up by Calypso when you 
forked in Oct.

I would post an issue with ldc but Calypso isn't up to date, so 
it might not be really fair as the fix may be in the newest ldc. 
I can't see anything standing out in the commits for an issue 
like this, but I might just be missing it.

Thanks,
Kelly



P.S. There is a small patch needed to compile on windows with 
VS2013. Things should still build fine on Linux with the patch.
