not set.

Is surrounding 'extern' declarations by #ifdef's really of any value?
They shouldn't be used if CONFIG_IDE_PROC_FS=n, so no object file
records should be generated.
Ah, you probably mean to turn the possible link time errors if the
do get referenced into the compile time errors...
Sorry, I don't quite understand that last sentence.
But we definitely
have compile time errors here because the compiler doesn't even know of
ide_proc_entry_t when CONFIG_IDE_PROC_FS is not set. Therefore the
forward declarations appear to be syntactically incorrect, regardless
whether extern or not.
