Hi,

I'm using the new CygWin B20 and try to create a dynamic object (not a DLL)
which I can access from another executable with dlopen and dlsym.

On Unix I would create this (linking stage) with:

g++    -Wl -shared -o dynobj.so  obj_file1.o obj_file2.o obj_file3.o ... -l...

But with CygWin B20 I get the following errors:

g++: unrecognized option `-shared'
C:\cygnus\CYGWIN~1\H-I586~1\bin\..\lib\gcc-lib\i586-cygwin32\egcs-2.91.57\..\..\
...\..\i586-cygwin32\lib/libcygwin.a(libcmain.o)(.text+0x58):libcmain.cc: undefined reference to `WinMain AT 16'

So first gcc doesn't seem to recognize the -Wl option so that the '-shared' option goes
to the linker. And of course in that case I have the problem that it seems to need WinMain
which is obviously not included in the objects.

How can I fix this?  Note that I DON'T want to make a DLL.

Greetings and thanks in advance,
