Hi,

libtool-1.5.6-3, cygwin 1.5.10(0.116/4/2)

I noticed the following today when trying to compile an application. 
Before I upgraded libtool earlier this week (not sure from which 
version, but a very recent one), this worked.

When you use '-export-symbols-regex "^[^_].*"', libtool generates a file 
according to:

/bin/nm -B  .libs/libxfce4util_la-i18n.o 
.libs/libxfce4util_la-licenses-texts.o .libs/libxfce4util_la-utf8.o 
.libs/libxfce4util_la-xfce-desktopentry.o 
.libs/libxfce4util_la-xfce-fileutils.o 
.libs/libxfce4util_la-xfce-kiosk.o 
.libs/libxfce4util_la-xfce-miscutils.o .libs/libxfce4util_la-xfce-rc.o 
.libs/libxfce4util_la-xfce-rc-config.o 
.libs/libxfce4util_la-xfce-rc-simple.o 
.libs/libxfce4util_la-xfce-resource.o  | sed -n -e 's/^.*[ 
]\([ABCDGIRSTW][ABCDGIRSTW]*\)[  ][ 
]*\(_\)\([_A-Za-z][_A-Za-z0-9]*\)$/\1 \2\3 \3/p' | /bin/sed -e 
'/^[BCDGS] /s/.* \([^ ]*\)/\1 DATA/' | /bin/sed -e '/^[AITW] /s/.* //' | 
sort | uniq > .libs/libxfce4util.exp
grep -E -e "^[^_].*" ".libs/libxfce4util.exp" > ".libs/libxfce4util.expT"

(sorry for the ugly way the lines are broken...)

The first part (nm -B ... > .libs/libxfce4util.exp) generates a file 
that looks like:

R _xfce_builtin_license_BSD xfce_builtin_license_BSD
R _xfce_builtin_license_GPL xfce_builtin_license_GPL
R _xfce_builtin_license_LGPL xfce_builtin_license_LGPL
_xfce_rc_config_close
_xfce_rc_config_flush
_xfce_rc_config_get_entries
...
_xfce_rc_simple_write_entry
parent_class DATA
utf8_string_remove_controls
xfce_desktop_entry_get_file
xfce_desktop_entry_get_int
xfce_desktop_entry_get_string
xfce_desktop_entry_get_type
...

I suspect that the "R _xfce..." lines are invalid. The 'parent_class 
DATA' line also looks suspicious to me.

Can the cygwin libtool maintainer please comment on this? Is this a bug, 
or should I adjust the regex passed to -export-symbols-regex?

Kind regards, Maarten
