Bugzilla Bug 114949

dosbox fails to build on amd 64. The following patch file needs to be applied
for it to work. The patch is taken from a newer version of dosbox cvs. All it
does is to change some unsafe casts.

Reproducible: Always

Proposed patch

I forgot to mention, this bug is about dosbox 0.63.

can you repost the patch using `diff -u` please

I got the patch directly from dosbox cvs. I'll take a look at it today after
work.

After more testing, I figured out that dosbox seens to be unstable on my
machine
w/ these modifications. Right now I'm using the cvs head version. I think it
might be safer to wait until 0.64 (it seems that the dosbox team will release
it
soon).

dosbox-gcc4.patch

This is all it took for me to get it to compile on 4.1.  It should work for
4.0.x too.

Sorry, it doesn't work for me:

dosbox-0.63-gcc4.patch

This is all I needed to change to get it to compile with gcc-4.0.2-r3

I did some testing and it seems that the unstability was caused by the binary
ati-drivers. I think the patches are safe.
