Actually, you were pointed at documentation that recommended submitting 
the bug into bugzilla.  Mail to gcc-bugs is likely to be lost, ignored, 
or misplaced.

It depends on the debug info.  linux is using dwarf, cygwin is using 
stabs.  You can reproduce it with the linux compiler by using -gstabs 
instead of -g.
