Cygwin fails with /c/ghcup/bin/cabal: No such file or directory #1264
Description
When trying to install from cygwin, the bootstrap-haskell script looks for cabal at /c/ghcup/bin/cabal. This is due to GHCUP_INSTALL_BASE_PREFIX being set to /c, yet in cygwin it should be /cygdrive/c.
Log:
$ ./bootstrap-haskell

[ Warn ] [GHCup-00110] ghc-9.6.7 is already installed; if you really want to reinstall it, you may want to run 'ghcup install ghc --force 9.6.7'

[ Warn ] GHC-9.6.7 appears to have no corresponding HLS-2.9.0.1 binary.
[ ... ] Haskell IDE support may not work.
[ ... ] You can try to either:
[ ... ] 1. Install a different HLS version (e.g. downgrade for older GHCs)
[ ... ] 2. Install and set one of the following GHCs: [9.10.1, 9.8.2, 9.6.6, 9.6.5, 9.4.8, 9.2.8]
[ ... ] 3. Let GHCup compile HLS for you, e.g. run: ghcup compile hls -g 2.9.0.1 --ghc 9.6.7 --cabal-update
[ ... ] (see https://www.haskell.org/ghcup/guide/#hls for more information)
