error messages, not the uninitialized string `str'. Love that
typechecking.
* strop.c (scm_substring_move_x): New function, which can handle
arbitrary overlapping substrings.
(substring-move-left!, substring-move-right!): These are
now just synonyms for substring-move!.
* strop.h (scm_substring_move_x): New prototype.
(scm_substring_move_left_x, scm_substring_move_right_x):
#define these as synonyms for scm_substring_move_x.
functions; capitalize the first letter of each word in the
argument string, and downcase the rest.
(scm_string_ci_to_symbol): string->symbol, such that the same
symbol is returned for any argument where the only difference
between strings is in capitalization.
(scm_string_upcase, scm_string_downcase): non-destructive
versions.
* strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
changed to use memmove.
* strop.c (scm_i_index): removed the pos arguments (it's only
called twice, and each time it's SCM_ARG1, SCM_ARG2, SCM_ARG3,
SCM_ARG4).
* strop.h: fixed prototypes.
* * strop.c (scm_substring_move_left_x, scm_substring_move_right_x):
changed to have 5 required args, rather than 2 required, and 3 required
rest args. Also modified to allow str1 & str2 to overlap.
(scm_substring_fill_x): changed to 4 args, rather than 2 args and
2 required rest args.
unif.c.
strop.h: move prototypes too.
* posix.c (scm_init_posix): don't intern EINTR since it's now done
elsewhere.
* ioext.c (scm_init_ioext): don't intern stat macros, S_IRUSR
etc. I deleted them from filesys.c long ago, but didn't
notice they were here too (although ineffective since
sys/stat.h wasn't included).
* read.c (scm_lreadr): use scm_misc_error to improve one of the
"unknown # object" error messages.
* strop.c (scm_i_index, scm_i_rindex): combine into one procedure
(scm_i_index) and declare it static. Add a 'direction' argument
to indicate what way the search should go.
(scm_i_index): throw out-of-range error instead of wrong-type-arg
if indices are bad.
(scm_string_index, scm_string_rindex): adjust usage of scm_i_index.
strop.h: remove scm_i_index, scm_i_rindex prototypes.
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).
