67 * call gettext () explicitely for actual "translation"

238 Although kpathsea seems nice, it is not universally available
241 Compiling kpathsea seems not possible without
242 (compiling) a matching tex installation. Apart from the fact
243 that I cannot get kpathsea compiled for GNU/Windows, another
244 major problem is that TeX installations may be different on
245 different clients, so it wouldn't work anyway. While ugly,
246 this code is simple and effective.
