load library problem

Hi folks,

I have flagged this before, but got no answer. Once again,
this a C++ Winelib app (one of the wxWindows samples):

[dimi at dimi calendar]$ ls calendar*
calendar      calendar_calendar.o     calendar.cpp  calendar.exe.so  calendar.o    calendar.rc           calendar-wrap.dll.so
calendar.bkl  calendar_calendar_rc.o  calendar.dsp  calendarM5.xml   calendar.pro  calendar_resources.o
[dimi at dimi calendar]$ export WINEDLLPATH=`pwd`
[dimi at dimi calendar]$ echo $WINEDLLPATH
[dimi at dimi calendar]$ wine --debugmsg +module,+loaddll calendar.exe.so  2>log

Error: Could not load the application's module calendar-wrap.dll (126)

The piece of code that fails is from the automatically generated wrapper[1].
Here is the part that fails:

I have the WINEDLLPATH set, what gives? Alexandre, I can't really track
this easily back, but I have a gut feeling it got triggered by one of
the reorganizations that you did around the loader...

[1] That is how the app was linked:
