wide character issues with gcc 3.2

[Anthony Feick]

Gcc 3.2 on linux compiles and links our app, but -fshort-wchar doesn't seem 
to be working completely.  The compiler directive 'L' converts character 
strings properly, and wchar_t is the right size.  The problem is that 
"basic_string<wchar_t>" still thinks everything is 4-bytes.

basic_string<wchar_t> foo = L"foo";
foo[0] is 'f'
foo[1] is 'o'
foo[2] is uninitialized

also

basic_string<wchar_t> bar;
bar.push_back((wchar_t)'b');
bar.push_back((wchar_t)'a');
bar.push_back((wchar_t)'r');
bar.c_str[0] is 'b'
bar.c_str[1] is 0
bar.c_str[2] is 'a'
bar.c_str[3] is 0
bar.c_str[4] is 'r'
bar.c_str[5] is 0

Also, GCC 3.2 on FreeBSD doesn't have definitions for wide character string 
functions (towlower, towupper, ...).  There is a "cwctype" in 
"local/include/c++/3.2/", but including it doesn't do anything.

If anyone can help me with either of these problems I would greatly 
appreciate it.  If there is a better mailing list to send this to, let me 
know.
