* Makefile.in (ancillary): List aclocal.m4, for 'make dist'.

* Makefile.in (ALL_CFLAGS): Don't mention CFLAGS here; it's
implicit in the .c.o rule.
(.c.x): Don't mention ALL_CFLAGS here; its value is included in
$(CC) already.

Put the library path in a header file, instead of passing it on
the command line in every compilation.
* Makefile.in (libpath.h): New target.
(feature.o): Depend on libpath.h.
(clean): Delete libpath.h.
(ALL_CFLAGS): Don't use -DLIBRARY_PATH here.  Instead ...
* feature.c: ... #include "libpath.h" here.
* .cvsignore: Ignore libpath.h.

Don't install the unwashed masses of Guile header files in the
main #include path; put most of them in a subdirectory called
'libguile'.  This avoids naming conflicts between Guile header
files and system header files (of which there were a few).
* Makefile.in (pkgincludedir): Deleted.
(innerincludedir): New variable; this and $(includedir) are enough.
(INCLUDE_CFLAGS): Search for headers in "-I$(srcdir)/..".
(installed_h_files): Divide this up.  Now this variable lists
those header files which should go into $(includedir) (i.e. appear
directly in the #include path), and ...
(inner_h_files): ... this new variable says which files appear in
a subdirectory, and are referred to as <libguile/mumble.h>.
(h_files): List them both.
(install): Create innerincludedir, not pkgincludedir.  Put
the installed_h_files and inner_h_files in their proper places.
(uninstall): Corresponding changes.

* __scm.h: Find scmconfig.h and tags.h in their new locations
(they're both "inner" files).
