Subject[PATCH][2.4] Speedup 'make dep'
From
Date

Hi Marcelo,

During 'make dep', make spends most of its time (sometimes more
than 75%) uselessly analysing .hdepend. Delaying its production
makes 'make dep' much faster.
The following patch also builds .depend last, in order to make
the dependency information generation more resistant against
^C and other failures.

Regards,

-- Benoit
