In Visual C++, it’s possible to use #pragma warning (disable: ...). Also I found that in GCC you can override per file compiler flags. How can I do this for “next line”, or with push/pop semantics around areas of code using GCC?

    It appears this can be done. I’m unable to determine the version of GCC that it was added, but it was sometime before June 2010.

    Here’s an example:

    #pragma GCC diagnostic error "-Wuninitialized"
    foo(a);         /* error is given for this one */

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wuninitialized"
    foo(b);         /* no diagnostic for this one */
#pragma GCC diagnostic pop

    foo(c);         /* error is given for this one */
#pragma GCC diagnostic pop 

    foo(d);         /* depends on command line options */
