nsTimerOS2.cpp

Timers are used to invoke a function or method after a specified time. The current implementation uses WM_TIMER to do this.

Look at removing PM dependency
If PM dependency stays, remove assumption that message queue exists in current thread. See Managing message queues.

nsFileSpecOS2.cpp

These classes are designed to provide a cross-platform abstraction of file names and conversion to file:// URLs (abstracting; see nsFileSpec.h for more).

The OS/2 version is pretty-much non-functional at the moment due to confusion about how it is supposed to work; in progress.
