Note that these warning will occur *if and only if* you use gcc4, which 
is still not yet the default in many distributions. As unusual as it is 
for Debian :-) , in this case the default compiler of Debian is a higher 
version than what many other people use. Most other distributions still 
ship with gcc 3.3.x or 3.4.x as default. Please bear this in mind when 
complaining about compiler warnings -- most other developers here do not 
(yet) see this particular warnings.

Besides, you can switch off this particular annoying 
"pointer-signedness-warnings" by -Wno-pointer-sign. That is probably the 
best option for you.

... and this can be switched off by -Wno-unused or more particular

Yes, macros with different numbers of argument clearly is an error that 
cannot be ignored. The above warnings, however, can be ignored so far.

I would advice against -Wno-error but rather switching off those 
particular warnings as described above. OTOH of course goffice shouldn't 
be fixed by us but rather by upstream.
