[Bioc-devel] RCurl on Windows

It's not something I need, per se, but what other packages that depend on
RCurl need. This issue was brought to my attention because someone on the
support site had a problem with the UniProt.ws package, which uses RCurl to
download data. Given the reverse dependency tree for RCurl I assume this
problem will have an outsized effect, at least amongst Windows users.

I know that DTL wrote the package back in the day, but apparently the CRAN
maintainers have been de facto maintainers/authors since 2013. So I sent
them the same reproducible error. Anyway, there isn't a current version on
Github (there is a two-year old version at github.com/cran/RCurl), so there
isn't a more interactive way to report the error.
