Weird question, right?
Here's the problem.
Assume you have a file "foo.so" on Linux. If you call
dlopen ("./foo.so", RTLD_LAZY);
it succeeds, but
dlopen ("./foo", RTLD_LAZY);
fails because the dlopen function never adds any suffixes like .so
automatically.
Now assume you have a "foo.dll" file on Cygwin.
dlopen ("./foo.dll", RTLD_LAZY);
succeeds, but so does
dlopen ("./foo", RTLD_LAZY);
The reason is that Cygwin checks for the .dll suffix as well as the
Windows LoadLibrary function does.
For 1.7 our choice is to keep dlopen() checking for the .dll suffix to
be more Windows-like, or to be more Linux-like by dropping the check for
the .dll suffix so that dlopen() fails if the filename isn't specified
fully.
While we tend to change the implementation to be more Linux-like,
there could be some tools out there which erroneously depend on the
Windows-like behaviour of Cygwin's dlopen().
Does anybody know such a tool? If so, is there a chance to fix this
easily in that tool or do we have to keep up this behaviour? Finally,
is there another *good* reason to stick to the Windows-like behaviour
here?
