Hi there !

I have used djgpp (gxx v3.4.3). This time, I update to v4.0.1 and
install boost library (v1.33.1). When I compile a test program using
lambda header file, it shows error message "boost/lambda/lambda.hpp :
NO such file".  But I did modifty djgpp.env to add boost include path
for CPLUS_INCLUDE_PATH. How can I fix the problem ?

I modified CPLUS_INCLUDE_PATH in djgpp.env  like this :
CPLUS_INCLUDE_PATH=%/>;CPLUS_INCLUDE_PATH%%DJDIR%/lang/cxx;%DJDIR%/include;C:/Boost/include/boost-1_33_1
But it fails.

When I copy all the files and directories from
C:\Boost\include\boost-1_33_1\boost to C:\djgpp\include\boost to check
whether boost library itself is all right, it compiles successfully. So
boost library seems to be configured successfully but environment
setting in djgpp seems to be wrong.

The boost library is configured at:
C:\Boost\include\boost-1_33_1\boost
For example, lambda.hpp is located at
C:\Boost\include\boost-1_33_1\boost\lambda\lambda.hpp

The test program is as follows:
---------------- lambda.cpp -------------------------
#include  <iostream>
#include  <ostream>
#include  <algorithm>
#include  <boost/lambda/lambda.hpp>

int main()
{
	using namespace std;
	using namespace boost::lambda;

	int  v[ ] = { -25, -15, 0, 25, 15 };

	for_each( v , v + 5, ( cout << _1 << ' ') );
	cout << endl;

	for_each( v , v + 5, ( _1 += 10) );
	cout << endl;

	for_each( v , v + 5, ( cout << _1 << ' ') );
	cout << endl;

 	return 0;
 }
----------------------------------------------------------------------------

The command line is as follows :
gxx lambda.cpp

Thanks in advance.
