>Description:
std::ctype<char>::is gives apparently random results
for characters in the range 0x80-0xff (which have negative
values in char).
>How-To-Repeat:
Just compile and look at the output.  To see the correct
output, compile with g++ 2.95.2 using -DOLD (to suppress
the code using the new <locale>).   Two simple examples:
it says that ä is a digit, and that ç is a space.
>Fix:
The following change makes my test run correctly:
*** /opt/global/pkg/gcc-3.0.0_threads/include/g++-v3/sparc-sun-solaris2.7/bits/ctype_inline.h	Tue Jun 26 09:19:56 2001
--- bits/ctype_inline.h	Wed Oct  3 12:23:49 2001
***************
*** 37,43 ****
    bool
    ctype<char>::
    is(mask __m, char __c) const
!   { return _M_table[__c] & __m; }
  
    const char*
    ctype<char>::
--- 37,43 ----
    bool
    ctype<char>::
    is(mask __m, char __c) const
!   { return _M_table[static_cast< unsigned char >( __c )] & __m; }
  
    const char*
    ctype<char>::

I suspect that the same problem is present in other
functions; I only tested is.
