    Did you have any update on this? If there is a problem with MinGW-w64
    version, you can (just for experimentation) try UCRT demo build,
    which
    uses a newer version of MinGW-w64 than RTools 4:

So this worked with a patched version of wine. that fixed the above 
error. I'm waiting for that patch to go in and for the next wine 
release to try this again.
Thanks!

    Please note Brian Ripley has added/improved support for
    cross-compiling
    on Linux for Windows, so that it can be used for diagnosing LTO
    warnings
    (see NEWS in R-devel and src/gnuwin32/README.compilation). The
    cross-compilers and needed cross-compiled libraries for R itself are
    part of at least some Linux distributions (he tested on Fedora).

Yes very exciting!

    Microsoft is giving for free time-limited VMs primarily for testing
    Edge/MSIE, you can run them in e.g. in Virtualbox. As instructed
    in the
    VM, take snapshots often.

We have a Jenkins box that we use to spinup AWS windows sessions when 
we need to thoroughly debug now but ty for the info!

    Being able to test R on Wine may be useful, if you figure it out, I
    would be interested to learn more. It is easier to obtain, may be
    easier
    to automate, and some low-level bugs may be easier to diagnose. Of
    course, for the price of sometimes seeing errors not present on real
    Windows.

Do you think there would be more false positives or true negatives? 
That was my one big concern since it's just emulating the actual 
windows software environment.
An (expensive) way to try out would be to run all CRAN/BIOC checks on 
Windows and in Wine and compare the results.? Things breaking in Wine, 
but not in Windows: hopefully often it would be clear immediately from 
Wine messages in many cases that it is a Wine issue. Also it may be a 
real problem that just does not map to a failure on Windows. Things 
working in Wine, but breaking in Windows, hopefully would be uncommon.

If Wine turns up usable for this, we could legally distribute a virtual 
disk with say R-devel and free applications needed by it, with a simple 
script that would just run a package check there on any Linux 
distribution. Maybe even as a docker/singularity image. This should make 
it easy and fast for Linux users to check their packages (of course, 
this can't replace completely testing on Windows, and there is 
winbuilder and rhub, too).

That is in addition to the added flexibility of debugging the low-level 
bugs having the source code for the "OS".
