Proposing to call setlocale( LC_ALL, "C" ) in msSetup()

[Szekeres Tamás]

I have added

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1762

for this problem
and we have also a C# specific bug

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=1758

in connection with it.

I would suggest to enable/disable this feature by a compile switch.

I think we'll need a bug report to document the change and the reasons 
behind it (perhaps a copy of the thread where this was discussed with 
Frank).

Also, is it worth saving the original locale value in msSetup() and 
restoring it in msCleanup()? I realize that in most cases this won't be 
of any use, but I thought I would bring up the idea anyway.

Finally, a note about this should probably be added to the MapScript 
docs (SWIG and PHP docs) since this can potentially cause side-effects 
in scripting environments. I can take care of the PHP docs once the 
change is done.
