Such a command looks promising.
* I find it safer when double ampersand will be used as control operator
instead of semicolon there.
* I get the impression from an other command like "find . -name '?akefile' -exec ack --with-filename EXTRA_CFLAGS '{}' \;"
that the suggested parameter "EXTRA_CFLAGS" will not achieve an effect
at places where I am interested in at the moment.
It seems that further fine-tuning can become interesting and challenging
for involved make variables.
Regards,
Markus
