Folks,

I would like to encourage *not* setting LC_NUMERIC as it will often break
libraries that mapguide and fdo depend on, such as GDAL and PROJ.  I'm
working on making GDAL safer in the face of odd numeric locales, but at
the very best it will still be dangerous and will break some format
drivers, and services.

PROJ is also distinctly not numeric locale safe, though I will try and
address this too sooner or later.

Best regards,
