What should I do when building Emacs again with different configure options?

[Xue Fuqiao]

Hi,

The INSTALL file says:

--8<---------------cut here---------------start------------->8---
If you want to build Emacs again with different configure options,
first clean the source directories:
      make distclean
      ./configure
--8<---------------cut here---------------end--------------->8---

Does it mean I have to run a pure `./configure' before using a different
configure option?  E.g.,

--8<---------------cut here---------------start------------->8---
make distclean
./configure
./configure --this-time-it-is-a-different-option
--8<---------------cut here---------------end--------------->8---

or just run `make distclean' and use the different option?

I've searched the archives/web, but didn't find a question with close
relations to mine.
