Noted.

On cygwin the shared libraries are using the SO_MAJOR_VERSION
by long time.

cd /usr/bin

$ ls cyggcc*dll
cyggcc_s-1.dll cyggccpp-1.dll

$ ls cygfo*dll
cygfontconfig-1.dll cygform-10.dll cygform-8.dll cygformw-10.dll
cygfontenc-1.dll cygform7.dll cygform-9.dll

In this way we allow coexistence of several release, similar to

/usr/lib/libpq.so.5
on unix.
