cannot do case-insensitive search

[Sanjeev Jahagirdar - MD6 ~]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.1 (rs6000-ibm-aix4.1.5.0, X toolkit)
 of Mon Nov 20 2000 on frc0000
configured using `configure  --prefix=/usr/intel/pkgs/emacs/20.7'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

This version always does case sensitive searches. I tried setting/resetting the 
case-fold-search variable. But it did not help.

Thanx,
Sanjeev
