Hi there,
See my post few weeks ago (29/10/2002)
subject : conflicting types for `typedef struct mbstate_t`(was link troubles
with wcslen)
also the one from zhang le on 27/10/2002
missing wcsncmp,wcscpy,wcsncpy and more...
or a search in the archives on wcslen
no one on the list acknowledged the pb (cfg ?) and i noticed that gcc-3.2-2
probably solved issue 2) of my post because it had the following comment
(msg [ANNOUNCEMENT] Updated: gcc-3.2-2 10/11/2002):
'However, the only noticeable change from the last release was an attempt to
correctly define mbstate_t.'
I'm positive that wcslen is in newlib but i'm not sure for
wcsncmp,wcscpy,wcsncpy as i didn't needed them a that time.

Hello all,
Having happily upgraded my Cygwin to include gcc 3.2, I've
encountered a show-stopper: The linker can't resolve symbols
involving wide C++ strings. Here is an example:
#include <string>
#include <iostream>
using namespace std;
int main(int argc,char *argv[])
{
std::string<wchar_t> test;
}
-----------------
$ g++ test.cpp
/cygdrive/c/DOCUME~1/nigels/LOCALS~1/Temp/ccHP4AMl.o(.text+0x25):test.cpp:
undefined reference to `std::basic_string<wch
ar_t, std::char_traits<wchar_t>, std::allocator<wchar_t>
>::basic_string[in-charge]()'
/cygdrive/c/DOCUME~1/nigels/LOCALS~1/Temp/ccHP4AMl.o(.text+0x30):test.cpp:
undefined reference to `std::basic_string<wch
ar_t, std::char_traits<wchar_t>, std::allocator<wchar_t>
>::~basic_string [in-charge]()'
collect2: ld returned 1 exit status
---------------------------
Any hints, suggestions, or duh-read-the FAQ responses, appreciated.
Note that the following compiles & links:
int main(int argc,char *argv[])
{
std::string<double> test;
}
----------------
