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

$ g++ foo.cpp
$ ./a.exe
$ echo $?
5
I get the following from strace. This shows that the initialization path

is coming from.
0 0 [main] cc1plus (9284)

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?
