	In linux-2.4.6-pre8, there are only three configuration variables
that are defined with an indented 'define_bool' statement
(CONFIG_BLK_DEV_IDE{DMA,PCI}, and CONFIG_PCI), and the conditional
code execute by all "if" statements in all of the config.in files
appears to be indented (or at least the first statement in the block
is indented).  None of these three variables has the semantics that
I think you you described above.

	If you want to check, I determined this by the following shell
commands:

% find . -iname config.in | xargs egrep dep_tristate | tr '   ' '\n\n' | egrep '^\$CONFIG_' | sort -u > /tmp/config-dependencies 
% find . -iname config.in | xargs egrep '^[   ].*define_bool' | fgrep -f /tmp/config-dependencies  | awk '{print $(NF-1)}' | sort -u
CONFIG_BLK_DEV_IDEDMA
CONFIG_BLK_DEV_IDEPCI
CONFIG_PCI
% find /usr/src/linux/ -iname config.in | xargs egrep -A 2 ^if | egrep -v -e -- | egrep '^-[^         ]'
%
