Re: [ros-dev] msvc build update

[Ros Arm]

Hello,

Would you care to comment on "unefficient" regarding the trap rewrite, please?
The code is more efficient than previous assembly code, and more finely tuned than
Windows' own code, which wasn't updated since 1989 when it was first designed (and
is full of non-pairing, hazardous operations that were efficient only on a 486).

I also resent the hackish statement.

Perhaps GCC Extended Assembly is hard to understand? I would be happy to walk you through
it.

Finally, in any team project, it is efficient to subscribe to SVN notifications and keep
track of the project status. This way it would've been clear that a trap rewrite was
in progress, and we could have worked together.
