libcurl issue with cargo

[Jeremy Drake]

I'm trying to get rust and cargo working on Cygwin (as github user
@Berrysoft is getting it going on MSYS2), and I wanted to direct the curl
maintainer's attention to https://github.com/curl/curl/issues/17262.  I am
hitting this now with cargo on Cygwin with curl 8.13.0-1.  There was a
workaround applied in MSYS2 in
https://github.com/msys2/MSYS2-packages#5374, perhaps it could be
considered for Cygwin as well, unless some better fix can be devised?
