Sravan,

I don't think this aspect of the project has changed in years. Did you use the same msys/
mingw toolchain when compiling GDAL 2.0 and GDAL 2.2 ? I suspect not

In configure.ac, the relevant snippet is :

dnl ---------------------------------------------------------------------------
dnl Check whether we need to add specific suffix for executables (.EXE when
dnl building for Windows). This test should work for the case of
dnl cross-compilation too.
dnl ---------------------------------------------------------------------------
case "${host_os}" in
    cygwin* | mingw32* | pw32*)
      EXE_EXT=.exe
      SO_EXT=dll
      ;;
    *)
      EXE_EXT=
      ;;
esac


I suspect that your toolchain is identified a bit differently.

Could you open "configure" in a text editor and add the following lines at the end of it :

echo "-------------------------"
echo "Host OS: '${host_os}'"
echo "-------------------------"

Then run configure again and report the value displayed

For example with the x86_64-w64-mingw32 cross-compilation toolchain (host: Linux), I get 
the following, which matches the above expressions

-------------------------
Host OS: 'mingw32'
