I can fix the problem by changing lines 104-7 in instances.hpp, eliminating the
template specification <BOOST_REGEX_CHAR_T> after the constructor.  E.g., change
line 104 to:

template reg_expression<BOOST_REGEX_CHAR_T>::reg_expression(const
BOOST_DEFAULT_ALLOCATOR(BOOST_REGEX_CHAR_T)&);

I don't know whether the compiler is wrong or whether this change might break
the code for other compilers.  If the compiler is at fault, I will report it to
Digipaqard (or whatever they are calling themselves this week).
