Ah... now I see.  If (unsigned char)'X' > 127, then (int)(signed
char)'X' != (int)(unsigned char)'X'.  That didn't appear to me
before.  Thanks for the enlightenment!

In defense of the Linphone developers, their code wasn't as silly as
mine: a function receives a char*, and examines its input.  I'll
report this to them.
