* scmsigs.c (usleep): Clean up oddities declaring usleep; since
we're just using it, not redefining it, we can use a K&R style
declaration here.
(sleep): Declare this, too, if the system hasn't.
(scm_sleep, scm_usleep): Use scm_thread_sleep and
scm_uthread_sleep if they're available; otherwise, just call the
system functions.
* scmconfig.h.in: Regenerated.
* coop.c (sleep, usleep): Remove declarations; we don't use or
redefine these any more.
(scm_thread_usleep, scm_thread_sleep): New functions which do the
job of usleep and sleep in a thread-friendly way. We can use
these in the rest of Guile. Define versions for systems both with
and without iselect.
* coop.c (scm_thread_sleep): Make `slept' an unsigned long.
* coop.c (coop_sleephelp): Remove ANSI #ifdef hair.
* configure.in: Remove tests for usleep's argument type; we only
need that if we're going to replace it.
* acconfig.h (USLEEP_ARG_TYPE): Delete. All the other SLEEP
garbage is needed just to use usleep and sleep without compiler
warnings.
* configure: Regenerated.
as does the return type. We really shouldn't be redefining usleep
at all, but I don't have time to clean that up before the 1.3.
release. It's on the schedule for afterwards. (Thanks to Julian
Satchell.)
* coop.c (usleep): Use USLEEP_ARG_TYPE in prototype and
definition.
* scmsigs.c (usleep): Use USLEEP_ARG_TYPE in prototype.
* scmconfig.h: Regenerated.
starting with guile_cv_; ac_cv_ is autoconf's namespace.
The type of the argument to usleep varies from system to system,
as does the return type. We really shouldn't be redefining usleep
at all, but I don't have time to clean that up before the 1.3
release. It's on the schedule for afterwards.
* configure.in: Cache results from usleep return value test.
Test for the type of the usleep argument, and cache that too.
* acconfig.h (USLEEP_ARG_TYPE): New macro.

here; first, NetBSD doesn't #define it, and second, it's the wrong
way to go about these things.
(dld_find_executable): Delete this MSDOS support code. This isn't
the way we want to support this; it needs to be rethunk at a
larger scale.
* GUILE-VERSION: Set to 1.2.90. This would appear to be a
regression from 1.3a, but everyone knows that the next release is
1.3, I want to switch to a more coherent version numbering system,
and now is the time.
(eq? #f '()) assumptions. Make functions that aren't documented
to return anything else return the queue itself. (Bug report from
Michael Livshin --- thanks!)
fports.c; don't just throw them together anywhere.
* fports.c (scm_stdio_to_port): Make NAME a SCM value, which is
what the rest of Guile wants. Don't set the revealed count;
that's only appropriate for stdin, stdout, stderr.
(scm_standard_stream_to_port): This function does set the revealed
count.
* init.c (scm_init_standard_ports): Use scm_standard_stream_to_port,
not scm_stdio_to_port.
* filesys.c (scm_open): Call scm_stdio_to_port; don't write it out.
* fports.c (scm_open_file): Same.
* posix.c (scm_pipe): Same.
* socket.c (scm_sock_fd_to_port): Same.
* ioext.c (scm_fdopen): Same.
(scm_freopen): Moved from here to...
* fports.c (scm_freopen): ... here. This is really something that
munges the internals of an fport, so it should go here.
* fports.h (scm_stdio_to_port): Adjust prototype.
(scm_standard_stream_to_port, scm_freopen): New protoypes.
* ioext.h (scm_freopen): Prototype removed.
scm_evict_ports, scm_open_file, scm_stdio_to_port): Get rid of
SCM_P macro.
Do magic to mix reads and writes on stdio FILE-based ports.
* fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY):
New macros.
(pre_read, pre_write): New functions.
(local_fgetc, local_fgets, local_ffwrite, local_fputc,
local_fputs): Call them.
(local_fflush): Mark the port as ready for reading and writing.
(scm_stdio_to_port): Set the FPORT_READ_SAFE, FPORT_WRITE_SAFE
flags on new port objects. This might not be accurate --- who
knows what state the FILE * is in when we get it --- but it won't
do extraneous calls to fflush or fseek, so it's no worse than the
behavior before this change.
* ports.h: Add comment.
Centralize the creation of port objects based on stdio FILE * in
fports.c; don't just throw them together anywhere.
