Hello Devs,

my SA install used in conjunction with MySQL for the userpref store, does not use the locale settings. Especially, the locale decimal point doesn't get payed tribute.

My MySQL backend table does contain the follwoing entry:
 Nico Prenzel/pn-systeme	required_hits	5,4	1520110

but a simple test with my user 
 /usr/bin/spamc -R -d 192.168.253.5 --username "Nico Prenzel/pn-systeme" < sample-spam.txt

does result in a required score of 5.0:

1002.5/5.0

If i do change my userpref to the following
 Nico Prenzel/pn-systeme	required_hits	5.4	1520110

then my test outputs a needed score of 5.4:

system locale:
$ LANG=de_DE.UTF-8 locale -k LC_NUMERIC LC_MONETARY | grep decimal_point
decimal_point=","
mon_decimal_point=","

perl's locale:
#!/usr/bin/perl

use POSIX qw(locale_h);

# Get a reference to a hash of locale-dependent info
$locale_values = localeconv();

# Output sorted list of the values
for (sort keys %$locale_values) {
    printf "%-20s = %s\n", $_, $locale_values->{$_}
}

decimal_point        = .


Is this the intended behaviour, or a misconfigured perl?
Is SA always using the "minimum C locale"?


Thanks.
