Re: help- URGENT build errors while using gcc

Thanks Joe,

I did find a workaround for the collision, by using #undef for stl pair and 
set, Though i was wondering why the pair definition for stl pair got 
included when i had not used the std:: namespace;
That was a doubt which i was hoping that you would help me clear and you did 
thanks, are you saying that if i had used the gcc 3.0 compiler the compiler 
would not have reported this as an error?(iam using gcc 2.95 here for doing 
the builds)

Bye,
Radhika

You're perhaps dismissing this guy too quickly, Mike.

The people on the other C++ lists will correctly tell you that this is a
gcc 2.95.x bug, that The STL's "set" and "pair" are supposed to be in the
std namespace.  This problem has been fixed in 3.0.  With gcc 3.0 or
another conformant C++ compiler, if you don't issue any "using"
directives, then the names for the STL datatypes are std::set and
std::pair.

Just the same, I'm sure people on comp.lang.c++.moderated can show you
awful tricks with the preprocessor to work around this kind of problem.
