Follow-up Comment #2, sr#110989 (group autoconf):
No, if I understood Nick and Jacob's suggestions correctly, the idea is to
replace $am_sleep / AT_MTIME_DELAY with something like
while [ ! newer_file -nt older_file ]; do
sleep $am_cv_filesystem_timestamp_resolution
touch newer_file
done
But we need a Perl helper to implement that, because test -nt isn't in POSIX,
and a test implementation that does support -nt will probably be comparing
'struct timespec's directly rather than converting to 'double' first as Perl
does. My current vague plan is to make it be a special mode of autom4te,
autom4te --ensure-newer newer_file older_file
It could also be a separate helper script like move-if-change or automake's
"missing".
