code, so we can use the load-path to find the ice-9 boot code;
this makes it easier to run Guile without installing it. See
corresponding changes in guile/Makefile.in.
* feature.c: Move stuff concerned with the load path to load.c.
(scm_compiled_library_path): Deleted.
Don't #include libpath.h here.
* feature.h: Don't mention scm_compiled_library_path.
* load.c: #include "libpath.h" here, as well as <sys/types.h>,
<sys/stat.h>, and <unistd.h> (if present).
(R_OK): #define if the system hasn't deigned to.
(scm_loc_load_path): New variable.
(scm_init_load_path, scm_sys_search_load_path,
scm_sys_try_load_path): New functions.
(scm_init_load): Initialize scm_loc_load_path to point to the
value cell of the Scheme %load-path variable.
* load.h: Add declarations for scm_sys_search_load_path,
scm_sys_try_load_path.
* Makefile.in (feature.o, load.o): Dependencies updated.
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.

(they're both "inner" files).
