* 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.
* THANKS: Added Rob Collins and Chuck Wilson for their cygwin
work.
From Robert Collins <robert.collins@itdomain.com.au>:
* configure.ac (AC_EXEEXT): Needed for DOSish systems.
* libtool.m4 (shlibpath_overrides_runpath) [cygwin]: Set to yes

hack, so we just say the pic is the default.

library normally.
[cygwin]: Declare C++ compiler characterisics for g++, taking into
account the new auto-import support in cygwin ld.

eliminating duplicate -lgcc's from the link line.

libm and *-ncr-sysv4.3* requires libmw
* ltconfig.in: don't check for LoadLibrary, hardcode dlopen
configuration for BeOS and Cygwin
* ltmain.in: fix sourcing of .la files on Solaris
(patch by Raja R Harinath)
this has a negative side-effect of causing automake to add MATHLIB
to every single Makefile. Let's use plain AC_CHECK_LIB, so that
LIBS get set, until we find a better alternative

add include_expsyms to the exported symbols
recognize it and fail, better keep using AM_PROG_LIBTOOL until the
next release of automake

* depdemo/configure.in, mdemo/configure.in: ditto
* demo/configure.in: likewise
* depdemo/configure.in: likewise

* mdemo/configure.in: likewise
* libltdl/ltdl.c: in find_module() check whether libdir is defined,
tryall_dlopen(): move deallocation of an already opened handle
to lt_dlopen(), allocate the directory in lt_dlopen() dynamically,
minor cleanups, fixed memory leak (name)

compatibilty, updated AC_SYS_NM_PARSE (no undefined symbols,
don't count the symbols)
