Subject: problem with string class (not string.h vs. String.h)

I just downloaded and installed beta 19.1.  No problems, everything
went fine.  I've been using it to work through "C++ Primer", 3/e (good
book, LOTS of misprints this edition), generally without problems
(i.e. templates, etc. work fine).

However...

This won't work, and it works fine on other compilers (i.e. g++ v. 2.8.1
running
on a DEC Alpha):

in file test.cc:

#include <string>

int main()
{
   string str( "string" );
   return 0;
}

I get a whole list of errors that look like the following:

mrsteve >> g++ -lg++ -I/Cygnus/b19/include/g++ -o test test.cc
C:\Cygnus\B19\H-i386-cygwin32\lib\gcc-lib\i386-cygwin32\2.7-B19\../../../libstdc

st.cc: first defined here

(plus about nine more multiply defined class methods, constructors, etc.)

As can be seen from the command line above, this problem is not solved by
linking against the g++ library, or by explicitly including the g++ include
directory.  I would LOVE to know what the problem is.   The error messages
seem to indicate that something is being multiply defined/included, but I've
been
through the header files some (the #include recursions get pretty hairy
after a bit),
and I couldn't find any obvious problems.

The version info is

mrsteve >> g++ -v
Reading specs from
C:\Cygnus\B19\H-i386-cygwin32\lib\gcc-lib\i386-cygwin32\2.7-B

and

mrsteve >> uname -a
CYGWIN32_NT CROAKER 4.0 19.1 i686 unknown

Any help would be much appreciated -- thanks in advance!
