[opendx-dev] patch for module loading

[Stephane Popinet]

Dear all,

In the current implementation (at least in 4.2.0) dynamic modules are
loaded using 

handle = dlopen(foundname, RTLD_LAZY);

which prevents the symbols defined within a module to be exported for
latter re-use (either by a latter module or by a module itself loaded
within the current module: which is what I need for my particular
application). I propose the following patch which fixes the problem
(for SunOS-style dynamic loading).

Any comment welcome,

All the best,

Stephane
