Yeah, it may bring problems.  This is why the configure script installed by
the package just checks for things that are unlikely to change over time
(like functions in libc, system headers, size of standard types, etc).  Of
course the user might add a check to cache if gtk2 is present, for example,
but that will surely bring problems when updating and/or removing the package.

I don't think remember things like "maximum command length", "readdir_r is
not present", "err.h exists" can bring problems.  And if it does, it's really
easy to rebuild the cache with up-to-date results.
