wstring and wchar_t usage with gcc

[lrtaylor@micron.com]

Did you just simply edit that header file and then try to recompile your
program?  If so, then that is to be expected, since wide support
probably was not compiled into the compiler.  You're probably going to
have to rebuild your compiler with support for wide characters so that
these functions can get defined.

Thanks,

hi,

My code using wstring and wchar_t does not compile. 
I realized that  "_GLIBCPP_USE_WCHAR_T" was undefined in c++config.h
file 
and defined it.

 It cleared the first error ( i guess) but resulted in further errors
like 
below  from the cwchar header.
 
/gcc/3.2.1/include/c++/3.2.1/cwchar:137: `btowc' not declared
/gcc/3.2.1/include/c++/3.2.1/cwchar:142: `fwide' not declared
/gcc/3.2.1/include/c++/3.2.1/cwchar:143: `fwprintf' not declared
/gcc/3.2.1/include/c++/3.2.1/cwchar:144: `fwscanf' not declared
/gcc/3.2.1/include/c++/3.2.1/cwchar:147: `mbrlen' not declared

Can someone tell me what needs to be done?

Thanks
