Hi, I have noticed that installed libtool (configured for MSVC tools) was producing invalid .la files. I have discovered it when I tried to build ncurses with MSVC. However, we have recently have discovered configuration issue related to configure trying to find a Fortran compiler. This caused building libltdl to fail. I believe this configuration issue is also responsible for this behavior (invalid .la files). After I started passing FC=no and F77=no to libtool's configure script, I noticed that installed libtool script started behaving as expected. - Kirill Makurin
