Re: Suggestion for MSVC build

The .def files can be generated from cygwin or mingw's dlltool command:

erase readline.def
erase history.def
dlltool --export-all-symbols -z readline.def libreadline.a
dlltool --export-all-symbols -z history.def libhistory.a
lib /machine:i386 /def:readline.def
lib /machine:i386 /def:history.def

(note: dlltool won't overwrite a def file if it exists).

But why would this be necessary? It looks like the readline
distribution is broken.
