Compiling errors occure, when --enable-discover-only.(On both parted-2.3 and parted-1.8.8)

[ChenMin]

Hi,

Compiling errors occure, when --enable-discover-only is set.
If "--enable-discover-only" isn't set, the parted-2.3 can be builded successfully.
parted-1.8.8 still cann't be compiled successfully with --enable-discover-only.

I would like to use libparted library on an embeded platform, and only a subset features of libparted are needed.

Following is based on parted-2.3.

I met 3 errors, 2 compilation errors and 1 linking error.
