File list hash not updated

[Doug Shea]

        I'm seeing an odd behavior, and can't figure out what it might be. We using VPATH, and we're using it to find source files. One of the directories in the path only has two files in it when the make begins, but gets populated with more source files by a rule along the way.

        Here's the thing: on many machines, future rules to compile those files find them properly, using the VPATH. On other machines, they do not compile because gmake can't find them; but if gmake is run again, the VPATH file hash is populated with the files properly, and they build fine.

        It seems that the correct behavior is to act like the one that does it all in one pass; the VPATH hash apparently becomes updated when those source files are created in that directory. Can anybody think of why the other machines are not doing this?

        We're using gmake 3.77, the same binary on both machines; the same behavior occurs if we try 3.79.1. The 'working' cases have all been on Windows 2000, and 'non-working' cases have been on Windows 2000 and Windows 98. I can provide 'gmake -d' and 'gmake -p' output from both cases, if anybody wants to look at them. Any hints or suggestions would be helpful. Thanks!
