Subject: [PATCH] libxtables: compiler warning fixes for NO_SHARED_LIBS

Fixes two issues with NO_SHARED_LIBS:
|
||
|
|
- #include <dlfcn.h> is ifdef'ed out and thus dlclose()
|
||
|
|
triggers an undeclared function compiler warning
|
||
|
|
- dlreg_add() is unused and thus triggers an unused
|
||
|
|
function warning
|
||
|
|
|
||
|
|
Test: builds without warnings
