using the CommonC++ library in WIN32

[Massimo Balestri]

Hi all,
(sorry for any duplicate e-mail, I don't know exactly which reflector is 
currently in use);
I am trying to use CommonC++ 1.4.2. on a set of WIN32 machines (98, NT, 2000).
I use VC++ 6.0 (SP4) to compile the library.
I can compile the library without problems, but when I try to use it, each 
time I include
"thread.h" I get the following level-1 warnings:
--------------------------
Compiling...
threadtest.cpp

'waitThread' : inconsistent dll linkage.  dllexport assumed.

'setException' : inconsistent dll linkage.  dllexport assumed.
Linking...
-----------------------------------
Then the simple example runs without problems, but I suppose that this is 
not a good sign.
My impression is that more complex examples could go into troubles.
Attached is the test code (a very simple code...)

with kind regards,
Massimo.
