GetModuleFileNameA is available on all platforms, and besides, you use
it without checking if it's NULL.

+/* Try getting the long path of your module name */
+  if(pGetLongPathNameA) {
+    ok(pGetModuleFileNameA(NULL,tmpstr,sizeof(tmpstr)),"GetModuleFileNameA
failed %s\n",
+       tmpstr);
+    todo_wine ok(pGetLongPathNameA(tmpstr,tmpstr1,MAX_PATH),"GetLongPathNameA
failed %s\n",
+       tmpstr);
+  }

What is this testing?  Just that GetLongPathName doesn't fail in this
case (I'm not even sure what 'this case' is specifically)?  You should
be checking the return value and the value of the out variable.
