configure error

[Tijl Coosemans]

I get the following error running configure on FreeBSD:

config.status: creating Makefile
sed: 14: ./confstathEGAkR/subs-4.sed: unescaped newline inside substitute pattern

There's one of those for every Makefile. The problem is with the
following lines in configure.ac where I had to add '\\' to every line
to work around the problem. Is this a FreeBSD only thing?

AC_SUBST(DEPENDENCIES,"### Dependencies:\\
\\
.INIT: Makefile\\
.BEGIN: Makefile\\
Makefile: dummy\\
	-\$(MAKEDEP) -C\$(SRCDIR) -S\$(TOPSRCDIR) -T\$(TOPOBJDIR) \$(EXTRAINCL) \$(DEPEND_SRCS)\\
