Version 4.0.0a3 does not compile with default '-Werror' flag

Hi,

I had to remove the default '-Werror' flag from the Makefiles because
otherwise I could not get it to compile here. The OS is Solaris 10 and I
tried it on both, Sparc and x86 architecture. GCC version is 3.4.3 and I
used configure with its default values and no custom compiler flags.
I included the warnings I get with '-Wall' (GCC seems to be fine with the
rest) and also 'config.h', because at least 'discover.c' depends on the
defined variables to decide which prototype to include (I haven't looked
into the other files).

Regards,

Marcus
