* NEWS: Updated.
* 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. * depdemo/l1/Makefile.am: ditto. * depdemo/l2/Makefile.am: ditto. * depdemo/l3/Makefile.am: ditto. * depdemo/l4/Makefile.am: ditto. * mdemo/Makefile.am: ditto. * tagdemo/Makefile.am: ditto. * demo/Makefile.am: ditto. But also, we must make special provision to clean up the hell0 wrapper script. * pdemo/Makefile.am: ditto -no-undefined. ditto hell0. And use 'hell_static' instead of 'hell.static'. * tests/pdemo-inst.test: use 'hell_static' instead of 'hell.static'. * tests/pdemo-exec.test: ditto.

$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.
|

* depdemo/l1/Makefile.am: ditto.

* tagdemo/Makefile.am: ditto.
|

* demo/Makefile.am: ditto. But also, we must make special
|
||||
provision to clean up the hell0 wrapper script.
|
||||
* pdemo/Makefile.am: ditto -no-undefined. ditto hell0.
|
||||
And use 'hell_static' instead of 'hell.static'.
|
||||
* tests/pdemo-inst.test: use 'hell_static' instead
|
||||
of 'hell.static'.
|
||||
* tests/pdemo-exec.test: ditto.

LoadLibrary.
|
||||
* Support auto-import patch to binutils on cygwin for much improved dll

support.
