//  we can end up with cyclic dependencies with some std lib implementations.

// Important: there are no include guards on this header for Borland C++

// The Borland version of <exception> has some peculiar circular dependencies

// that requires multiple inclusion.  Likewise for gcc (gcc-2.95.3 fix).
