digitalmars.D.bugs - setlocale not working as expected

reply "Frank De prins" <fdp mcs.be> writes:
Hello,

When I use setlocale with LC_ALL it does not seem to work.
I use nlb_belgium and, when I print (writeln in console) a 
floating point number, I expect the decimal separator to be a 
comma.  But it remains a dot.
When I use 0 instead of LC_ALL, it does work.
So I inspected the values defined for those locale cateory 
constants and they seem to be completely different from what I 
find in the Visual C++ headers.  Is this possible?  I mean, are 
they not expected to be the same, or is this vendor specific?

PS: This is how they are defined in VC:

#define LC_ALL          0
#define LC_COLLATE      1
#define LC_CTYPE        2
#define LC_MONETARY     3
#define LC_NUMERIC      4
#define LC_TIME         5

Also, in VC++, the return value of setlocale is defined as char* 
whereas, in D, it is int.  This makes it impossible to inspect 
the current locale.

Best regards and thanks for a wondderfull language,

This list is not intended to be posted to directly by anyone but bugzilla 
itself. If you have a bug, please report it at d.puremagic.com/issues (in 
which case, that would be messaged to this list). If you have a question about 
learning D, then post to digitalmars-d-learn, and if you have a general D 
question then, post it to digitalmars-d.
