Comment (by Petr Machata <pmachata@â¦>):
Curiously, no, I can't, it doesn't seem to be documented, but it's been
supported since "forever". It's used internally by stdlibc++, and boost
even uses this syntax in a couple places (move, type traits). With GCC
3.3, which is the oldest that I have around, I'm getting this:
{{{
__attribute__ ((__noinline__)) int ble() { return 10; } // passes
quietly
__attribute__ ((__sdkfljlk__)) int ble2() { return 10; } // gives
warning
}}}
(Hopefully I typed this correctly, the machine that I tested this on is
not networked.)
The code in boost is not incorrect, it just lends itself easier to user-
defined macros. The underscore syntax is supported by GCC to remedy this.
Please consider applying the patch.
