1) I'm going to beat everyone else to the punch and suggest you go here:
https://cygwin.com/problems.html

In particular, a cygcheck output looks like it might be useful.

2) Can you please convince your mail program to put in a line break 
occasionally?

3) I think I disagree with you that your install is not the issue, since 
your test program compiles and runs perfectly for me.

I did change the return value to 5 for testing purposes.

$ cat > foo.cpp << EOF
 > int main() { return 5; }
 > EOF
$ g++ foo.cpp
$ ./a.exe
$ echo $?
5

I don't see any initialization path stuff in my strace. I suspect you 
have an old cygwin1.dll somewhere, and running cygcheck as described on 
the "Reporting Problems" page linked above will likely point that out.

Are you running cc1plus directly?
