The "share" directory holds platform-independent files, while "lib" holds platform-specific files. In principle, the "collects" directory belongs in "share", as does "doc". Those directories are put into "share" by a Unix-style install, but left at top level for an in-place install. Packages in installation scope are put in "share" instead of "lib", and the top-level Makefile puts development links in "share/devel-pkgs". The `configure' script now supports `--docdir' and `--collectsdir'. Changed the version to 5.90.0.1.
