When I asked this question a while ago, I got answer like "use
AC_{COMPILE,LINK,etc}_IFELSE macros family instead of AC_CHECK_{HEADER,
LIB, etc}". Although I still think, this way is not quite convenient,
but nevertheless it works. Another possible way is to 'unset'
appropriate cache variables (like 'unset ac_cv_header_oci_h') between
two subsequent tests but 'unset' is marked as being non-portable.

Hmm, I thought this code is much older...
