tcl7.3-XPG.patch

Tcl and XPG localization are currently incompatible.  The follow patch offers
a solution to this problem.

The problem:

   If setlocale is called to enable XPG localization, the behavior of all
functions that convert or format floating point numbers may changed.  Tcl
stores all floating point numbers as strings and does conversions as needed.
If a European numeric locale is specified, then these functions expect the
decimal point to be ",".  Any floating point number in a script must be in
the form "3,14158".  To make matters worse, then Tcl returns a floating point
number, it attempts to keep it from reverting back to an integer, thus you
would end up with "3,14158.0"

A solution:
   When the first Tcl interpreter is created, setlocale is called to force
the global use of the "C" locale.  This forces all library functions involved
in formating and converting floating point numbers to be behave as expected.

   Two new commands have been added to allow formating and converting numbers
using the current locale, they are "nlformat" and "nlscan" ("nl" for native
language).  They are identical to the format and scan commands, except that
they use the current locale for numbers outputted (nlformat) or inputed
(nlscan).  With a the LANG variable set to a German local, you get the
following results:

%nlformat %f  3.14159
3,141590
% nlscan 3,14159 %f x
1
% echo $x
3.14159
