Re: C2220: warning treated as error (64 bit MSVC 2015)

2016-05-25 Thread slacka 
With sberg's and Noel's patches, I can now build the 64-bit version again.
Nice work team!

To answer my own question, the C4334 warning is new in VS 2015 Update 2.

C2220: warning treated as error (64 bit MSVC 2015)

2016-05-20 Thread Luke Benes 
With the LODE environment, I can build the 32-bit binary without any errors. 
Recently, the 64-bit builds stopped working. For 64-bit I get the following 
error:

I tried to bisect it, and couldn't build anything as far back as I tried. Could 
this be from an update to my OS (Win 10) or MSVC?
The following incorrect/bad hack allowed me to build it:
