Oops, sorry. I read your reply as saying "you should really have a
toolchain with thumb support enabled".

Yeah, I would like to have thumb interworking support enabled in the
libraries. If you know how, please tell. But as I said (poorly), I think
it will work OK as long as my library has thumb support and I'm careful
not to call any library functions from non-thumb functions.
