Well, the version of OpenSSL you're using, for one thing. And what C
implementation; there are various ones which can be used under Cygwin. Cygwin
is an environment, not a build toolchain.
I don't know if this is still true, or if it differs for 1.1.1 and 3.0; but
historically there have been issues using Cygwin perl to build OpenSSL, because
OpenSSL on Windows wants a perl implementation that uses Windows-style file
paths. We use Strawberry Perl.
That said, that error appears to be due to an issue with the Windows SDK
headers, since it's the Windows SDK which should be typedef'ing LONG. (Because
we wouldn't want Microsoft to use actual standard C type names, would we?) So
this might be due to not having some macro defined when including the various
Windows SDK headers.
