latest binutils spits on some assembler files the following message

we believe the source of the problem might come from gcc.

There is some code that uses DosWaitEventSem. In particular, PR_WaitCondVar. Using PR_WaitCondVar in a GUI thread of a PM app will effectively block not only this app but the whole PM due to the SMQ (single message queue) syndrome. See ​https://github.com/bitwiseworks/mozilla-os2/issues/225 for a real life example.

Using WinWaitEventSem instead of DosWaitEventSem fixes the problem and makes PR_WaitCondVar PM-friendly. However, this brings a dependency on PMWIN.DLL to NSPR4.DLL which will make it impossible to use apps linked against NSPR4.DLL in a PM-less environment (i.e. when CMD.EXE or another application is used as a protmode shell instead of PMSHELL.EXE and PMWIN.DLL is not available at all).

To avoid this, we should load WinWaitEventSem dynamically and use DosWaitEventSem as a fallback.
