Hello all,

I'm new to both cygwin and STL.  I tried looking in the mail archives to
find some resolution to this, but none of the problems I found in there
seemed to address what I'm seeing here (though it's entirely possible that I
didn't completely understand the contents of some of those archived
messages).  So, with that in mind...

I try compiling the following program (which is using STL) in B20, under
WinNT (SP5) by using gcc version 2.95:

==================================

// stl_test.cpp

#include <vector>

using namespace std;

void main(void)
{
  vector<double> t1(3);
}

==================================

and it generates the following error message during compilation:

==================================

g++ stl_test.cpp

`_imp___ctype_' follow
collect2: ld returned 1 exit status

==================================

It compiles fine in MSVC 6.0 and Linux (Mandrake release 6 on kernel
2.2.9-27mdk using pgcc-2.91.66).  Any insights would be very helpful?
