Cygwin is a collection of many programs and scripts. Some of them don't
support spaces in directory names. Therefore, it is advisable to avoid using
spaces.
The default home dir is not in "Documents and Settings". Cygwin is noticing
that you have HOME set in your environment, and using that. You probably
don't want that. Why is HOME set?

This sounds like out-of-date info to me (but that's just a guess).

There seems to be a bug in Cygwin.
The following are unrelated to the bug:
- HOME directory
- "| tail -"
- WinMainCRTStartup
- gstr
- -mwindows
I have snipped your testcase appropriately.
You can easily show that the bug is in Cygwin, as it does not occur when the
testcase is compiled with -mno-cygwin.
