--- Comment #8 from Sandro Mani <manisandro at gmail.com> ---
I've looked around a bit and can't really find much, except that besides
autotools also qmake appears to do it by default, as I gather from [1].

As an experiment, I looked at all dlls of all Fedora mingw packages:

$ dnf provides '/usr/x86_64-w64-mingw32/sys-root/mingw/bin/*.dll' | grep
Filename | awk '{print $3}' | sort | uniq > dlls

$ cat dlls | wc -l
714

$ cat dlls | grep -Ev '[0-9].dll' | grep -v "^Qt5" | wc -l
343

So out of 714 dlls, 343 have no versioning.

A strong argument for versioning IMO is that from a packaging point of view it
enforces versioned dependencies between packages, i.e.:

$ rpm -q --requires mingw64-gdal
mingw64(iconv.dll)
mingw64(kernel32.dll)
mingw64(libcfitsio-3.dll)
mingw64(libcurl-4.dll)
mingw64(libexpat-1.dll)
mingw64(libfreexl-1.dll)
mingw64(libgcc_s_seh-1.dll)
mingw64(libgeos_c-1.dll)
mingw64(libgeotiff-2.dll)
mingw64(libgif-7.dll)
mingw64(libgrib2c.dll)

mingw64(libjasper-4.dll)
mingw64(libjpeg-62.dll)
mingw64(libkmlbase.dll)
mingw64(libkmldom.dll)
mingw64(libkmlengine.dll)
mingw64(libpcre-1.dll)
