I’ve just got  a new laptop (the old one’s hard disk died) so I’m trying to get to the point of being able to build GHC again.
I’m currently stuck here:
configure: loading site script /usr/local/etc/
checking for gfind... no
checking for find... /usr/bin/find
checking for sort... /usr/bin/sort
checking for GHC version date... inferred 8.5.20180323
checking for GHC Git commit id... inferred affdea82bb70e5a912b679a169c6e9a230e4c93e
checking for ghc... /c/fp/HP-8.2.2/bin/ghc
checking version of ghc... 8.2.2
GHC path canonicalised to: c:/fp/HP-8.2.2/bin/ghc
checking build system type... x86_64-pc-msys
checking host system type... x86_64-pc-msys
checking target system type... x86_64-pc-msys
Unknown OS msys
Any ideas?
