help with disabling warnings

[John Qyindi]

Hi,

I'm trying to get some code up and running that another developer sent
but am getting many warnings when compiling it.  I don't want to
change the code as I don't want to introduce any differences from his
original code.

So I tried the #pragma disable_warn in the code for now but g++ then
says

warning: ignoring pragma disable_warn

... 

is this pragma not compatible with the -Wall argument ?  

Thanks.
