Hi,
When should AC_CACHE_CHECK be used? Whenever the user uninstalls
something, wouldn't the cache become invalid?
...only if the user happened to uninstall something during the configure
process. After that, AC_CACHE_CHECK is irrelevant.
But if the user uninstalls libfoo then later re-runs ./configure,
won't libfoo still be assumed to be installed?
sure. That sort of thing was why (for a long time) autoconf removed
the cache on startup. Now that you're mentioning it, I seem to recall
a recent undoing of that.
