I'm leaning towards the inline InterlockedCompareExchange from
winbase.h, as if I rebuild ntdll with -O1 miscemu/wine is built
correctly (ie ntdll doesn't have any undefined references). It's from
win32/device.c and win32/except.c which call
InterlockedCompareExchangePointer(), which itself calls
InterlockedCompareExchange() from winbase.h.

"extern inline InterlockedCompareExchange() {return bar();}" seems a bit
odd for a function definition. What the purpose of having both extern
and inline?

The whole point might be moot regarding linking, as ntdll is not
required for miscemu/wine (see below).

See above. BTW, ldd doesn't show kernel32.

Yes, ntdll is the first thing to be loaded.

Hmmm... I guess the -lntdll.dll on the linking line of miscemu/wine is
the cause :)
I've been able to link it while removing that part, so I'm not sure if
that part is still useful.
