I recently ran across some sample code in section 19.4 of the Autoconf
manual (modified slightly to reduce example):
$(TESTSUITE): $(srcdir)/testsuite.at $(srcdir)/package.m4
autom4te --language=autotest -I '$(srcdir)' -o $@.tmp $@.at
mv $@.tmp $@
This question isn't about autotest, but rather about the two commands in
this rule - why generate the output into $@.tmp and then mv $@.tmp into $@?
Is there some power mv has over autom4te that allows it better access to
the target under some conditions?
Thanks in advance,
John
