The class RWCRegex does not have the { } parameter defined in the class. You will need to use the RWTRegex<T> class to use the {} functionality. Here is a sample of the code you have using the RWTRegex<T> class:

#include <iostream>
#include <rw/cstring.h>
#include <rw/tools/regex.h>

int main()
{
RWCString a("AA098765");
RWTRegex<char> re("^[A-Z]{2}[0-9]{6}$");
RWTRegexResult<char> result;
result = re.search(a);
std::cout << "result: " << result.subString(a) << std::endl;

return 0;
}

This is the output as expected:
result: AA098765
