even `if FALSE' *_SOURCES should be used for TAGS

[Jan Kratochvil]

Hi,

it came on now on the binutils mailing list:

`make tags' will not index sources which are listed in *_SOURCES += ... in
unsatisfied AM_CONDITIONAL blocks.  IMO they should be.  Sure one can use some
EXTRA_*_SOURCES out of the `if' block but this delocalizes+duplicates the
information making error prone for future modifications.

OTOH AM_CONDITIONAL can be used for example if an optional sources part is
/ is not bundled, in such case the current automake behavior is better.

Posting here for a consideration as asked about by Ralf Wildenhues.


Thanks,
Jan
