Bug#944431: Segfault on startup

Hello Markus, hello Enrico,
I am sorry to be late, but I guess I have found the issue.
The function SetThreadPriority does not return properly
therefore the following function gets executed which writes
to somewhere, that causes later the crash below.
The build logs show a warning for this issue:
tmp/compat_mini.cpp: In function ‘int SetThreadPriority(THREAD_HANDLE, int)’:
tmp/compat_mini.cpp:106:1: warning: no return statement in function returning non-void [-Wreturn-type]
106 | }
| ^
Attached patch adds return statements for all functions
currently triggering this warning.
Kind regards,
Bernhard
