Feel free to attach any such patch to the bug in mantis:

I'm attaching (here and at the bug) a script I use to configure and
build an e-mail library for both the iPhone simulator (x86) and the
iPhone itself (arm).  There's some extraneous junk in there but you
should get the idea.  The important flags are '-arch armv6' and
'-isysroot /path/to/sdk'.  It might also be worth mentioning that
Apple prohibits the use of dynamic libraries in iPhone apps (for now
at least) and most iPhone projects are built in Thumb mode by default.
