The dlfcn.h file from the source distribution never made it into
the cdk.exe.  You need to get the cygwin32 sources from the same
place as you got the cdk and copy the dlfcn.h file into
$CYGWIN_ROOT/H-i386-cygwin32/i386-cygwin32/include.  Then dlopen
and friend will (mostly) work as usual.

Geoffrey, I notice that the dlopen emulation doesn't handle a NULL
argument as per the POSIX spec (i.e. return an introspective handle
to the current process), yet the win32 GetModuleHandle does... will this
be fixed for b20?  Too late for a patch?

Cheers,
