Move code to initialize and search %load-path from ice-9 to C 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.
