* Per #2272 and #1877, MinGW has issues when delay loading libraries, but it is possible to apply a workaround to alleviate them, by redefining DECLSPEC_IMPORT before including the corresponding headers. * This is a bit more tricky to accomplish for virtdisk, as MinGW's windows.h header does include virtdisk.h on its own (rather than expect a formal include as MSVC does), so we have to prevent the virtdisk.h inclusion first, by defining a macro, and then apply our workaround. * Per https://sourceforge.net/p/mingw-w64/mailman/mingw-w64-public/thread/ea87573f-65ea-44a2-b4bb-ca96c0a136ab%40akeo.ie/#msg58793876 we are hoping that this should be a temporary workaround and that the root cause of the issue will be fixed in binutils. * Closes #2513.
