-An installation of GHC requires about 50M of disk space (which can be lowered by choosing a “compact” installation). The Cygwin support tools take another 200M or so (though if you really need to this can be halved by installing only the following packages: bash, binutils, cygwin, diff, fileutils, findutils, gcc, grep, make, perl, mingw, sed, textutils, w32api; however, it's fiddly and not recommended). To run GHC
-comfortably, your machine should have at least 64M of memory.
