I’ve setup cgywin64, with the packages described here: [https://github.com/JuliaLang/julia/blob/master/doc/src/devdocs/build/windows.md](https://github.com/JuliaLang/julia/blob/master/doc/src/devdocs/build/windows.md)
Done a `git clone --branch release-1.4 https://github.com/JuliaLang/julia.git`
Run `echo 'XC_HOST = x86_64-w64-mingw32' > Make.user`
And build with `make -j 8`
This has worked OK with Julia 1.7 branch, but not with the julia 1.4 branch. It gives the following err:
What do I need to change to make it work?

The URLs are in the .mk files
e.g. [https://github.com/JuliaLang/julia/blob/release-1.4/deps/pcre.mk](https://github.com/JuliaLang/julia/blob/release-1.4/deps/pcre.mk)
[https://github.com/JuliaLang/julia/blob/release-1.4/deps/blas.mk](https://github.com/JuliaLang/julia/blob/release-1.4/deps/blas.mk)
and those third parties have changed the location so they are no longer present at those addresses
You will have to hunt them down manually and copy them to srccache yourself (or fix the .mk files and submit a PR)
