As far as I understand it:
1. Make everything.
2. Build a tarball from the build result, using the files
mentioned in the Makefile.am.
3. Create three subdirs (SOURCE, BUILD, INSTALL or whatever the
exact names are).
4. Extract the tarball into SOURCE.
5. Unprotect BUILD, write protect SOURCE and protect INSTALL from
any access.
6. cd into the builddir, build everything with --srcdir=SOURCE and
--prefix=INSTALL.
=> This makes sure that all files built are placed in BUILD,
all source files are taken from SOURCE, and nothing is
installed or built in INSTALL during the build step.
7. Protect SOURCE from any access, write protect BUILD and
unprotect INSTALL.
8. make install
=> This makes sure that installing actually places the files
in INSTALL and not elsewhere.
9. make uninstall and check that nothing is left in INSTALL
except empty directories.
=> Check that everything put into INSTALL ist removed, and that
files are actually removed from the INSTALL and not from
SOURCE or BUILD.
If "make distcheck" fails, it's normally either because some file
is missing from the tarball or not properly uninstalled.
