* m4/libtool.m4: protect quotes in cygwin's
$postinstall_cmds and $postuninstall_cmds, which were
broken by gvv change of 2003-10-21.
Okay, I am applying a more general patch to try to fix this problem for all
variables passed to `config.status'. Can you check that everything behaves
for you please?
Cheers,
Gary.

Index: ChangeLog
from Gary V. Vaughan <address@hidden>
* m4/libtool.m4 (AC_LIBTOOL_SETUP): Add a new
delay_single_quote_subst sed script to quote single quotes in
variables that are copied to `config.status'.
(_LT_CONFIG_STATUS_DECLARE): New macro to apply
delay_single_quote_subst to a named variable.
(AC_LIBTOOL_CONFIG): Use _LT_CONFIG_STATUS_DECLARE to declare all
`configure' variables that are copied to `config.status'.
(AC_LIBTOOL_PROG_COMPILER_PIC): Fix a quoting bug exposed by
_LT_CONFIG_STATUS_DECLARE using the null quadrigraph in the
rvalues of lt_prog_compiler_pic.
