You don't need MSYS at all. You only need to install MinGW, Flex and Bison (can all be downloaded from the MinGW website). So simply download those three (in the same directory, e.g. C:\MinGW) and make sure to include MinGW's bin dir (e.g. C:\MinGW\bin) in the path environment variable (i.e. %path%). You can extract the dev-package anywhere you want, just make sure to set the DEVDIR setting in makerules/config.mk (derived from config.mk.tmpl) to the path where you extracted it to. (Also configure the rest of the settings in makerulse/config.mk before hitting `mingw32-make -f Makefile.raw'.
