Re: directory search fails!

[ali hagigat]

Philip, thank you to respond. Lets go through the details of the
manual step by step:
--------------------------------------------------------------------------------------------
4.4.3 How Directory Searches are Performed
The algorithm make uses to decide whether to keep or abandon a path
found via directory search is as follows:
1. If a target file does not exist at the path specified in the
makefile, directory search is performed.
2. If the directory search is successful, that path is kept and this
file is tentatively stored as the target.
--------------------------------------------------------------------------------------------
"this file is tentatively stored as the target"!!

What does it mean? Target file will be stored on hard disk? Where?
tentatively, what does it mean? What does non-tentatively mean?
