The first reason, that MSVC (Microshit Visual C--) isn't supported by
Libtool, still remains. People on this list might say why care about
MSVC - we've got Cygwin. However, the fact of the matter is, that
there's a large number of ROOT users out there that does use MSVC, and
have developed applications with MSVC that uses ROOT. These cannot
always easily be ported to Cygwin. Hence, it's crucial that the build
system support MSVC. An option could be to have separate build systems
- one using MSVC's build system, and Autotools for the rest. However,
that solution isn't acceptable to the upstream developers. The build
system need to work on _all_ supported platforms.
