Disabling updating of makefiles

[Colm Aengus Murphy]

Hi folks,

We are using Paul Smith's "Advanced Auto-Dependancy Generation"  
(http://make.paulandlesley.org/autodep.html) to great effect.
However as the number of source files increase make slows down.
The reason is that when you launch make it reads in an make file for 
each source file. This can take some time.
Then it tried to update them.
I have added a rule to speed up its decision to remake them but it still 
slows make down.

Is there any way to disable the updating of makefiles altogether ?

Has anyone else solved the scaleability issue with having a make file 
for each source file ?

The speed issue is most apparent on windows when make can take 20 
seconds before it even begins to check if it needs to update any object 
files.

We are already running with make -R to avoid make trying its own builtin 
rules (as an aside this option doesn't work in a MAKEFLAGS variable for 
some reason).

Regards

Colm A
