10-csw-cygwin-install-strip.patch

[Charles Wilson <cygwin at cwilson dot fastmail dot fm>]

On cygwin, 'make install-strip' in a libtoolized, automake-driven 
project ends up stripping the import library, instead of the DLL.  This 
is bad: not only is the DLL unstripped, but stripping an import library 
can sometimes break it, and make the installed lib unlinkable.

e.g. this command:

/bin/sh ../libtool --mode=install /usr/bin/install -c -s 'libgg.la'
'/usr/lib/libgg.la'

does the wrong thing.

The following patch was submitted on the cygwin list by Peter Ekberg. 
It fixes this problem, and incurs no regressions in the testsuite when I 
used it.

	* config/ltmain.m4sh (func_mode_install): on cygwin,
	ensure that import libraries do not get stripped.
	* m4/libtool.m4 (_LT_SYS_DYNAMIC_LINKER): on cygwin,
	use postinstall_cmds to strip DLL (not import lib)
	when stripping is requested.
