Changed rules to make SGML documentation using DocBook tools rather than
LinuxDoc.

DLL install support

Added support for dllwrap options

- define and use *_OPTS for the various sgmltools.
- acknowledge the existence of INSTALL_LIB_SCRIPTS.

AT_GLASGOW went away.

Added ZIP_OPTS

Renamed SRC_HC_{PRE,POST} to HC_{POST,PRE}_OPTS

New option variables: HC_PRE and HC_POST; $(SHELL) actions to perform before & after compiling a Haskell source file

Suppressing the generation of a default rule (-s) is a local property of a flex spec, not global

Added suffix rules, option variables, etc for greencard

Added INSTALL_BIN_OPTS plus default is to strip installed binaries

Major update to more-or-less 2.02
