nanosecond timestamp support in stat and utime
* libguile/posix.h:
* libguile/posix.c (scm_utime): Add optional nanosecond arguments. This
is an incompatible change on the C level, but it's unlikely people are
using this POSIX wrapper function, because they would just use the
POSIX function directly. Hopefully, anyway.
* module/system/base/compile.scm (call-with-output-file/atomic):
Propagate source timestamps to targets with nanosecond precision, if
available. Fixes build on systems with ext4 filesystems.
* libguile/filesys.c (scm_stat2scm):
* module/ice-9/posix.scm (stat:atimensec, stat:mtimensec)
(stat:ctimensec): Add three new elements to Scheme stat structures,
for nanosecond-level timestamps.
* configure.ac: Add checks for utimensat, and for nanosecond fields in
struct stat. We should switch to using Gnulib things for these,
though.
* doc/ref/posix.texi (File System): Add documentation for utime's
additional arguments, and nanosecond stat timestamp accessors.
