* libguile/print.c (scm_print_opts): Add 'r7rs-symbols' print option.
(symbol_has_extended_read_syntax): If the 'r7rs-symbols' option is
enabled, then disallow '|' and '\' from bare symbols.
(print_extended_symbol): Use 'scm_lfwrite' and 'scm_putc' instead of
'display_string' and 'display_character' when printing ASCII literals.
(print_r7rs_extended_symbol): New static function.
(scm_i_print_symbol_name): If the 'r7rs-symbols' option is enabled,
use 'print_r7rs_extended_symbol' instead of 'print_extended_symbol'.
* libguile/private-options.h (SCM_PRINT_R7RS_SYMBOLS_P): New macro.
(SCM_N_PRINT_OPTIONS): Increment.
* doc/ref/api-evaluation.texi (Scheme Write): Mention 'r7rs-symbols'
print option.

* libguile/private-options.h (SCM_R7RS_SYMBOLS_P): New macro.
(SCM_N_READ_OPTIONS): Increment.
* libguile/read.c (scm_read_opts): Add entry for 'r7rs-symbols'.
(t_read_opts): Add field for 'r7rs_symbols_p'.
(scm_read_string_like_syntax): New function based on earlier
'scm_read_string' that handles either string literals or R7RS quoted
symbols (delimited by vertical bars), depending on the value of 'chr'.
(scm_read_string): Reimplement based on 'scm_read_string_like_syntax'.
(scm_read_r7rs_symbol): New static function.
* doc/ref/api-data.texi (Symbol Read Syntax): Briefly describe the R7RS
symbol syntax, mention the 'r7rs-symbols' read option, and give some
examples.
* doc/ref/api-evaluation.texi (Scheme Read): Mention the 'r7rs-symbols'
read option.
* test-suite/tests/reader.test ("reading"): Add test.
* libguile/r6rs-ports.c (cbp_seek)[WHENCE == SEEK_CUR]: Break out of the
switch statement when OFFSET is zero.
Pass 'scm_wrong_type_arg_msg' a phrase suitable for use after
"expecting".
* test-suite/tests/r6rs-ports.test ("7.2.7 Input Ports")["custom binary
input port supports `port-position', not `set-port-position!'"]: New
test.
Fixes a bug introduced in cc1cd04f81
"Fix hashing of vectors to run in bounded time."
* libguile/hash.c (scm_hasher): Avoid division by zero.
* test-suite/tests/hash.test ("hash"): Add tests.
* libguile/hash.c (SCM_MIN): New macro.
(scm_hasher): In vector case, do nothing if d is 0. Make sure to
recurse with a reduced d. Move the loop out of the 'if'.
* libguile/ports.c (scm_i_port_property, scm_i_set_port_property_x):
Lock the port mutex while accessing the port alist.
* libguile/read.c (set_port_read_option): Lock the port mutex
while modifying port read options.
* libguile/gc.h:
* libguile/gc.c:
* libguile/deprecated.h:
* libguile/deprecated.c (scm_gc_live_object_stats): Deprecate; it hasn't
worked in the whole 2.0 series.
* libguile/private-gc.h (SCM_DOUBLECELL_ALIGNED_P): Remove; unused.
* libguile/filesys.c (MAX, MIN): Move definitions here, from
private-gc.h.
(scm_sendfile, scm_readdir): Adapt uses of SCM_MAX and SCM_MIN to use
MAX or MIN.
* libguile/fluids.c (new_fluid): Don't run an explicit GC for the first
fluid.
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE, scm_storage_prehistory):
Enlarge from 32 kB to 512 or 1024 kB, depending on word size. Reduces
startup time by 10 or 15% by avoiding excessive
GC.
* libguile/private-gc.h: Remove SCM_DEFAULT_INIT_HEAP_SIZE_2 definition
here.
* libguile/gdb_interface.h:
* libguile/gdbint.c:
* libguile/gdbint.h: Remove. These were last modified significantly in
1997 and I think they are unused.
* libguile/guile.c: Remove use.
* libguile.h: Remove inclusion.
* libguile/Makefile.am: Remove reference.
* libguile/init.c: Remove use.
* libguile/ports.c (scm_peek_char): Don't require error cases to
set *len. Fixes a bug caught by GCC whereby an EOF while reading a
multibyte character with iconv would leave len uninitialized.
* libguile/ports.c (scm_i_port_alist, scm_i_set_port_alist_x): Removed.
(scm_i_port_property, scm_i_set_port_property_x): New procedures,
available from Scheme as '%port-property' and '%set-port-property!'.
* libguile/ports.h (scm_i_port_alist, scm_i_set_port_alist_x): Removed.
(scm_i_port_property, scm_i_set_port_property_x): New prototypes.
* libguile/read.c (set_port_read_option, init_read_options): Adapt to
use scm_i_port_property and scm_i_set_port_property_x.
