It's very simple.  If you use the Cygwin gcc, by default it links with
cygwin1.dll, and the program will understand POSIX paths.  If you give a
"-mno-cygwin" option to gcc, you'll be using the MinGW libraries, and your
program will not understand POSIX paths (i.e., you'll have to use Win32
ones).

FYI, Cygwin programs always understand POSIX paths, even when executed
from a command window or a batch file.
