[New-bugs-announce] [issue9566] Compilation warnings under x64 Windows

Wed Aug 11 01:59:46 CEST 2010

New submission from Antoine Pitrou <pitrou at free.fr>:

A 64-bit build under Windows produces many compilation warnings, mostly related to lossy conversions between different int sizes.
Some of these warnings appear harmless after analysis (are MS 64 bit compilers pickier than their 32 bit counterparts?).
It would probably be spammy to open a separate issue per file.
