Build error with -Werror=cast-align on ia64

[fghaas]

Debian still builds on ia64, among other platforms. On ia64, we're getting a cast-align warning that breaks the build as we're building with -Werror. The problem is evidently in the do_list and do_command functions in src/main.c.

I'm also wondering if this warning indicates a real problem or not. If not, how about removing the -Werror ?;)

[fghaas]

You're the developer, you tell me. Silencing a warning just by disabling it sounds like less than a great idea to me.

Building with -Wcast-align doesn't only break on ia64, but on a bunch of platforms:

I suggest to either fix those warnings, or (if safe to do so) disable the cast-align warnings.

Disable cast-align warning should be safe, so fix it now.
