Is this a CRAN issue or a GPL issue? Several packages are actually
doing this already. E.g. all the windows binary packages that link to
static library, like the XML package to libxml2.
AFAIK the windows binary for XML contains a binary build of libxml2,
and I don't think the libxml2 sources are included anywhere in the XML
package.

I can't say anything for CRAN, but for the GPL, I think we are fine.

But if you think we are not, then yes, we can just put the pandoc
sources in the source package.
