Installing CygwinFor extra documentation please check the cygwin homepage
A complete install is recommended, but the 250MB complete download is only useful until Gentoo compiles all "system" packages.
The cygwin path structure emulates a UNIX system with root directory where you installed cygwin. So /home/ is mapped to C:\Cygwin\home if you installed Cygwin to C:\Cygwin.
Windows driveletters are mapped to /cygdrive/, so C: is /cygdrive/c/
