In my /usr/share/aclocal/libtool.m4:
| LIBM= 
| case "$lt_target" in 
| *-*-beos* | *-*-cygwin*)
|   # These system don't have libm
|   ;;

Does your libm.a really contains any functions, or is it an
empty archive ?

But maybe automake 1.4 is wrong.

No, all these functions are included in the System framework, so you
always get them.
