Avoid potential compilation error with old gcc

Browse Source 
The optional message for deprecated attribute is introduced in
gcc 4.5[1]. To avoid potential compilation error, we should check
gcc version before using it.

Also, __GNUG__ is for testing GNU C++ compiler. Therefore, we should
remove it as we are targeting C here.
