We no longer update LIBOBJS manually today.  See the `AC_LIBOBJ
vs LIBOBJS' section of the Autoconf manual.  Also `.o' should be
`$(OBJEXT)' if portability matters (but AC_LIBOBJ will do that
for you).

Here is what I'm using to check for getopt_long
http://www.gnu.org/software/ac-archive/htmldoc/adl_func_getopt_long.html

 Simon> In ./src/ I have getopt.h getopt.c getopt1.c

in yourprog_LDADD or yourlib_LIBADD.

Many "serious" packages do that to, so perhaps it's not worth the trouble.
