Wierd warning message

Can someone explain to me what this warning message means?

c:\program files\microsoft visual studio\vc98\include\map(93) : while
compiling class-template member function 'struct XmlFieldDef::Lookup
*&__thiscall std::map<class MyString,struct XmlFieldDef::Lookup
*,struct XmlFieldDef::MyStringCompare,
class std::allocator<struct XmlFieldDef::Lookup *> >::operator [](const
class MyString &) '

I'm having a hard time understanding it.

Thanks.

This is only half of the error message, telling you where the problem
occurs. Above it, there should be another half actually saying what the
problem is.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going to
land, and it could be dangerous sitting under them as they fly
overhead. -- RFC 1925

C4786 is annoying but harmless. You can safely ignore it. Put the
following at the top of your stdafx.h file, before including any STL
headers

#pragma warning (disable: 4786)

Most of the time, this will take care of it. If not, see
