Thanks again, John. Yes, I meant to write autoconf. Sorry about that.
When I enter the ./configure command with the extensions as suggested in
your email below, I get an error message from bsdtar.exe - Unable To
Locate Component i.e. 'This application has failed to start because
msys-lzma-1.dll was not found. Re-installing the application may fix
this problem.' I noticed that the dll related to msys-liblzma 5.0.3 and
bin msys-bsdtar version 2.8.3 were installed with MinGW and that the
similar file 'msys-lzma-5.dll' is located in the msys\1.0\bin folder.
