Hi, maybe the problem arises when you use ./configure --disable-nls See that in the file "auxiliar.h" the header "libintl.h" for NLS stuff is conditionally included. But when NLS is disabled, the macro "dngettext" stays with no definition, becoming implicit declared. So we have to provide a dummy for it, as for the other macros provided there, ok?
I'll fix this on next release, 3.04.
