I have recently downloaded the STL to use as a foundation for 
my development.  I have not yet used it with DJGPP but I have 
seen other posts here that it works great.

I have one question concerning the syntax of templates.  I have 
attempted to compile on a Sun machine running SunOS 5.4 and 
the SPARCompiler version 4.0.1 using C/C++ SC3.0.1 (that may
mean nothing to most of you and thats okay...)

For the following template syntax in the STL include file 
"function.h":

.
.
.
template <class Result, class Argument = Result>
struct constant_unary_fun : public unary_function<Argument, Result> {
  result_type val;
  constant_unary_fun(const result_type& v) : val(v) {}
  const result_type& operator()(const argument_type&) const { return
val; }
};
.
.
.

I get errors for the '=' as the compiler syas it is expecting a ','
or another class, etc.  My question is: Is the = sign in templates
a new and widely unsupported feature of templates?  If so, does djgpp
and gcc handle them correctly?  Is there work arounds for this as I 
am just learning the intracies of templates. 

Thanks in advance!
