Missing TR1 cmath functions

[John Maddock]

This test case:

#include <tr1/regex>

int main(){
std::tr1::regex_traits<char> t;
t.isctype('c', 0);
return 0;
}

Fails to compile with:

c:\mingw4\bin\../lib/gcc/mingw32/4.3.0/include/c++/tr1_impl/regex: In member 
function 'bool std::tr1::regex_traits<_Ch_type>::isctype(_Ch_type, short 
unsigned int) const [with _Ch_type = char]':
t.cpp:6:   instantiated from here
c:\mingw4\bin\../lib/gcc/mingw32/4.3.0/include/c++/tr1_impl/regex:542: 
error: array must be initialized with a brace-enclosed initializer
t.cpp:6:   instantiated from here
c:\mingw4\bin\../lib/gcc/mingw32/4.3.0/include/c++/tr1_impl/regex:550: 
error: 'const class std::ctype<char>' has no member named 'isspace'
c:\mingw4\bin\../lib/gcc/mingw32/4.3.0/include/c++/tr1_impl/regex:552: 
error: array must be initialized with a brace-enclosed initializer

Just let me know when you want me to shut up! :-)

Cheers, John.
