[Audacity-devel] config.cache question

[Matt B. <mbr...@hm...>]

Because of our multi-directory autoconf setup, I find that running
'./configure -C' (to enable config.cache) reduces running time for the
script from 125 seconds to 71 seconds.

Would it be a good idea to enable the cache-file option by default in the
config script?  I'm not quite clear on exactly what conditions can lead to
problems with the cache file, and whether we need to worry about that.

At the very least, perhaps the README should at least mention the -C
option.  It can't hurt to use it the first time configure is run, and it
can shave a whole minute from the build time.
