Subj: 	'make' question

Who owns make?  Can anyone give me a definitive answer to this?

In the make we use locally, for files (src and obj both) populated with
symbolic links (i.e. mklinks) does 'make' decide dependencies based on
the timestamp of a link or the timestamp of the file linked to.

I know that the DECwest folks applied a bug fix at one point to the 1.1
make they get from OSF to check the linked file and not the link; I'm
wondering what the behavior is of our make.

thanks...	-josh

I think this means it always does "stat" calls and never does "lstat" calls when it's checking out the times. I just did a little test: >>> Simple makefile pangloss[76] cat makefile.test testlink: testfrom ln -s testfrom testlink >>> create a test file pangloss[77] cp /dev/null testfrom >>> run make once, to create link pangloss[78] make -f makefile.test -d MAKE ENTRY (make -f makefile.test -d) at Mon Feb 7 17:31:30 1994 Reading internal rules. MAKEDIR=/ Current working directory for make is /var/tmp doname(testlink, 0) doname(testfrom, 1) Looking for Single suffix rule.
