Suppress specific warning in gcc 3.4

Getting a warning message as below which I am trying to get rid off

warning: initialization discards `const' from pointer target type

The code needs to stay as it is so in VS used Suppress Specific Warning but I was wondering if there is some way to do the same in gcc as well.

Using quite an older version of GCC compiler 3.4 all the other posts I have come across talk about higher versions. Some helpful posts-

How to supress specific warnings in g++

http://www.dbp-consulting.com/tutorials/SuppressingGCCWarnings.html

https://gcc.gnu.org/onlinedocs/gcc-4.1.2/gcc/Warning-Options.html

Tried using-

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wignored-qualifiers"
//< code that generates warning >
#pragma GCC diagnostic pop

But then the warnings increase-

: warning: ignoring pragma: push
: warning: ignoring pragma: "-Wignored-qualifiers
: warning: initialization discards `const' from pointer target type
: warning: initialization discards `const' from pointer target type
: warning: ignoring pragma: pop

look here: 

<gcc.gnu.org/onlinedocs/gcc/Option-Summary.html>;

for the list of the gcc options and look at: 

<gcc.gnu.org/onlinedocs/gcc/…;

for more detailed descriptions.

This link: 

<gcc.gnu.org/onlinedocs/gcc/Warning-Options.html>

has this to say: 

"Each of these specific warning options also has a negative form beginning ' -Wno- ' to turn off warnings; 

for example, -Wno-implicit ."
