which requires its config.site, to work correctly.

of executables, use the executable file extension from $EXEEXT.
* libtool.m4: use $NM to create the symbol list on cygwin, not
$ltdll_cmds as on mingw. For all tags, (and host=cygwin) set
allow_undefined_flag="" so that the --auto-import magic
works properly. For all tags (and host=cygiwn) set
always_export_symbols=no -- it is unnecessary thanks to
binutils' auto-export magic.
* libltdl/ltdl.c: Don't force cygwin to use the LoadLibrary
wrapper; use cygwin's builtin implementatino of dl*.
* cdemo/Makefile.am: the downside of unsetting
'allow_undefined_flag' -- we must include -no-undefined
in the _la_LDFLAGS variable.
