I wonder if this is related to the uint16_t vs. char16_t issue discussed 
in http://bugs.icu-project.org/trac/ticket/9717 when using C++11 
compilers. Depending how the 16-bit character type is defined in various 
places (ICU code and xetex code), you might run into a mismatch.

A workaround, in that case, might be to disable C++11 support with an 
appropriate -std=... argument to the compiler.

(A more complete fix might require digging through the various places 
where types are defined, to figure out where the incompatibility arises.)
