Q: what is foo?

I try "tclmsgque_LIBTOOLFLAGS" -> no change
I look into the "Makefile" and get

...
tclmsgque_la-context_tcl.lo: context_tcl.c
        $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --mode=compile 
$(CC) $(DEFS) $(DEFAULT_INCLUDES) $(INCLUDES) $(AM_CPPFLAGS) $
(CPPFLAGS) $(tclmsgque_la_CFLAGS) $(CFLAGS) -MT tclmsgque_la-context_tcl.lo -
MD -MP -MF $(DEPDIR)/tclmsgque_la-context_tcl.Tpo -c -o tclmsgq
ue_la-context_tcl.lo `test -f 'context_tcl.c' || echo 
'$(srcdir)/'`context_tcl.c
...
as you see only $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) are used ????
->I'm confused
the info page speek about
...
   If `LIBRARY_LIBTOOLFLAGS' is not defined, the global
`AM_LIBTOOLFLAGS' variable is used instead.
...

about LIBRARY_LIBTOOLFLAGS well even the "LIBRARY" prefix does not work
->I'm more confused

than I try AM_LIBTOOLFLAGS

and get the following error...

/bin/sh ../../libtool --tag=CC -tag=disable-static  --mode=compile ccache gcc 
-std=gnu99 -DHAVE_CONFIG_H -I. -I../..   -D_DEBUG  -I./../libmsgque -

libtool: unrecognized option `-tag=disable-static'
libtool: Try `libtool --help' for more information.
make: *** [tclmsgque_la-context_tcl.lo] Fehler 1

after a look inti the info page I change "-tag" to "--tag" ..

next try

now it works ...........

summary:

change:

        foo_LIBTOOLFLAGS = -tag=disable-static

into

        AM_LIBTOOLFLAGS = --tag=disable-static

than it is fine
