I have never successfully got C++ stuff to work on LM32. I have tried
compiling Qt4, but I have also run into what looked like corrupted code
problems and I suspect this comes from GCC bugs.

LM32 GCC is indeed in a bad state. I'm even trying to fix that right now
- at the time, the SVN head does not even build.

A few months ago, I rewrote this driver in the Git repository and it now
does support termios. The initial one was based on the lm32_evr port
which has other issues like this... and its author does not seem willing
to fix them.
