[boost] Re: Borland C++ Builder patch 4 released

Sorry to say that the output is now incorrect.  A2 instead of A 2. 
Checking the preprocessor output for this gives

/* Unit1.cpp 9: */int main() {
/* Unit1.cpp 10: */std::cout << "A 2" << &std::endl;
/* Unit1.cpp 11: */return 0;

which is again correct.  This is strange since I thought that bcc32 was 
just supposed to call cpp32 for the pre-processing.  I can submit this 
as a bug to Borlands QualityCentral if you like (but don't hold your 
breath).

Cheers

Russell
