couple of warning fixes

[Alexandre Duret-Lutz]

So let's see if this mailing-list works :)

This is what I get when I run automake 1.4f on my project
(you can fetch it from here if you need full details
ftp://heroes.sf.net/pub/heroes/prereleases/heroes-0.10b.tar.bz2):

~/projs/src/heroes %                                                 Err 1 #120

The `comment following trailing backslash' errors are generated
by some commented rules in Makefile.am, for instance:

# rule:
#       foo \
#         bar

where the backslash doesn't really hurts.  The first patch below
change automake to ignore trailing backslashes on commented lines.

The `uninitialized value' warnings come from source files whose
extensions aren't known from automake.  My setup looks as follow:

heroes_SOURCES = \
[...] \
prefs.c \
prefs.def \
prefs.h \
prefs.tpl \
[...]

BUILT_SOURCES = \
[...] \
prefs.c \
prefs.h \
[...]

prefs.h: prefs.def prefs.tpl
        $(AUTOGEN) -o h prefs.def

prefs.c: prefs.def prefs.tpl
        $(AUTOGEN) -o c prefs.def

Automake just doesn't know anything about the `def' and `tpl'
extensions.  (Am I wrong in putting such files in _SOURCES?)
The second patch below get rid of these warnings.

Note that I have not checked the testsuite (by host tends to
segfault under heavy load and this give too many false results
in the testsuite).
