I'm not Ralf, but I can see two different reasons:

  * not all versions may support the "weak" attribute

  * The Intel C compiler for Linux is supposed to be able to compile
    the Linux kernel.  New versions the Linux kernel do use weak
    symbols (possibly with this syntax) -- so maybe the Intel
    compiler would too.

The second is somewhat far-fetched.  Support for #pragma weak ... and
_Pragma("weak", ...) is likelier.
