Subject: Re: Question about g++

How are you trying to build this exe.  I have the same program,
and if I do a 
make hello, 
then it fails with all the erros you have listed.  This is a known
and reported issue with make, where under cygwin, make uses 
gcc for .cc source files instead of g++.  Chris Faylor has noted
the error, and made a fix.  Just not sure when it will be released.
If you want to just use g++, then you should probably give it 
a -o option:
g++ -o hello hello.cc
This will make an executable binary called hello (hello.exe under cygwin).

HTH
