This adds full Unicode strings as a datatype, and it adds some
minimal functionality. The terminal and port encoding is assumed
to be ISO-8859-1. Non-ISO-8859-1 characters are written or
input as string character escapes.
The string character escapes now have 3 forms: \xXX \uXXXX and
\UXXXXXX, for unprintable characters that have 2, 4 or 6 hex digits.
The process for writing to strings has been modified. There is now a
function scm_i_string_start_writing that does the copy-on-write
conversion if necessary.
To compile strings that may be wide, the VM storage of strings and
string-likes has changed.
Most string-using functions have not yet been updated and may break
when used with wide strings.

for scm ipv6 funcs, gcc 4 is picky about char* vs uchar*.
(scm_getsockopt, scm_accept, scm_getsockname, scm_getpeername,
scm_recvfrom) Use socklen_t, gcc 4 is picky about int* vs socklen_t*.
to fit scm_from_ulong_long, since that uses mpz_import anyway. Don't
bother trying to fit scm_from_ulong, not really worth the trouble if
addresses are more than 4 bytes usually.
locale strings instead of accessing their internals.
(scm_recv, scm_send, scm_recvfrom, scm_sendto): Use
SCM_I_STRING_CHARS and SCM_I_STRING_LENGTH instead of
SCM_STRING_CHARS and SCM_STRING_LENGTH.

SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or
scm_to_locale_string, etc.

above, plus scm_i_get_substring_spec.
net_db.c, fports.c, filesys.c, eval.c, deprecation.c, dynl.c:

to the new scm_from_* and scm_to_* functions.
SCM_INUM): Deprecated by reenaming them to SCM_I_INUMP, SCM_I_NINUMP
and SCM_I_INUM, respectively and adding deprecated versions to
deprecated.h and deprecated.c. Changed all uses to either use the
SCM_I_ variants or scm_is_*, scm_to_*, or scm_from_*, as appropriate.
ipv6_net_to_num to scm_from_ipv6, for converting from an IPv&
byte-wise address to a SCM integer. Changed all uses.
(ipv6_num_to_net, scm_to_ipv6): Renamed ipv6_num_to_net to
scm_to_ipv6 and added type and range checking, for converting from

or similar.
malloc.
* gc-segment.c (scm_i_get_new_heap_segment): remove cluster cruft:
only use SCM_MIN_HEAP_SEG_SIZE.

function
* ports.h: use scm_i_ prefix for port table and port table size.

iso. SCM*. This is needed for full GC correctness.

SCM_VELTS() return a const pointer
(SCM_VECTOR_SET): add macro.

replacement for `gh_get_substr()'.
* socket.c: Include `stdint.h' if available for the `uint32_t'
declaration.
* scmsigs.c (s_scm_sigaction): Initialize `chandler' (inhibits
compiler warning).
* backtrace.c: Include `lang.h' for GUILE_DEBUG conditional.
* configure.in: Include `win32-socket.o' in the list of object
files if networking is enabled on Win32.
2001-11-07 Stefan Jahn <stefan@lkcc.org>
* win32-socket.[ch]: New files. Defines Winsock-API error codes
and makes them available through Guile. That is because the
Winsock-API does not store its errors in `errno' and thus cannot
return error messages via `strerror (errno)'.
* socket.c (scm_init_socket): Initialize `win32-socket' part
here under M$-Windows.
* numbers.h: Added missing declaration of
`scm_sys_check_number_conversions()'.
* error.c: Local definition of SCM_I_STRERROR and SCM_I_ERRNO
and use in `(strerror)' and `(system-error)'.
* Makefile.am (EXTRA_libguile_la_SOURCES): Added
`win32-socket.[ch]' to extra source and header files.
