Fix build in C++0x mode

This fixes compiler errors (gcc 4.6 -std=gnu++0x on x86_64 Linux):

embedded/qwslock.cpp: In function `bool forceLock(int, int, int)':
embedded/qwslock.cpp:121:39: error: narrowing conversion of `semNum'
        from `int' to `short unsigned int' inside { } [-fpermissive]

(and equivalent errors in other lines/files)

Section 8.5.4/6
