Reset LC_NUMERIC in pj_init() about proj

I should also explain, how this bug happens.

Several multi-lingual applications, like QLandkarteGT, call pj_init() and pj_transform() internally. If projection is specified in form "+init=epsg:2393", file /usr/share/proj/epsg is parsed and datum parameters for 2393 are used. But they are stored with a dot as decimal point, while pj_init() already operates locale-specific decimal point (comma in my case). So atof() rounds float numbers to integers (it stops parsing at first dot met).
That is why I suggest to reset LC_NUMERIC.

As far as I can see, console utils from proj.4 don't have such issue, probably because they are not localized (don't use setlocale()).

I concur with your analysis and I have applied just a slight variation on the patch in trunk (a26eedd4 (SVN rev1630)).
