[Mono-dev] Cross-compilation on OS X host to Windows target

[Josh DuBois]

Hi all,

   I can't quite tell what the preferred method for patches is for new 
contributors: I take it that not every single patch is emailed here to 
mono-devel first, but I'm new so I figured I'd ping.

   I'm trying to cross-compile a Windows version of mono using mingw-w64 
from an OS X host, but I get failures with undefined __int64.  (My 
reason for compiling in such an odd fashion is a desire to build the 
wine-mono project on my Mac).

   Including <stdint.h> allows me to build without issue.  It looks like 
doing this causes mingw to define __int64.

   I see mono has a build test server which tests on supported 
platforms, but it looks to me like that's post-commit.  Is there a way 
for me to submit the patch to the build test to ensure it doesn't break 
on other supported platforms?

   Do people think there's a better way to solve the problem?

   I submitted a pull request from my fork here: 
https://github.com/mono/mono/pull/560

   My patch is attached as a diff in case people want to kibbitz.

   Cheers,

            Josh.
