Subject: Add `extern "C"` to export in plugin/gdiplus
X-Git-Tag: 2.42.0~187^2~1
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=378e9a68322f5931ff8f94e5731c805b54c8c280;p=graphviz

Add `extern "C"` to export in plugin/gdiplus

plugin/gdiplus is a C++ project, so the `extern "C"` must be added in
order to export C symbols that can be used by the rest of the code.
