Is it possible to abort compilation from the code?

[Hitmark7]

Hello.

I'm writting a program for several targets, but some features are not available for all of them. I would like to abort the compilation if another programmer tries to use these features on the wrong target. I'm using conditional compilation this way:

#if neko
    return neko.Web.getURI();
#elseif php
    return php.Web.getURI();
#else
   <Insert here something that aborts compilation "gracefully", maybe even with a custom error message>
#end

Any ideas? I would hate to intentionally write a malformed expression in order to raise a syntactic error.

Thanks!
