gettextize provides a local file called "gettext.h". Remove this and use <libintl.h> from glibc headers instead. Most of this change is mechanical: #include <libintl.h> in every C file which uses any gettext function. But also we remove the gettext.h file, and adjust the "_" macros. Note that this effectively removes the ./configure --disable-nls option, although we don't know if that ever worked.
