Sorry, htable is the only one which is GPL.  hash is public domain.  The
rest are LGPL:

array_size/_info: * License: LGPL (2 or any later version)
asearch/_info: * License: LGPL
build_assert/_info: * License: LGPL (2 or any later version)
cast/_info: * License: LGPL
compiler/_info: * License: LGPL (3 or any later version)
endian/_info: * License: LGPL (2 or any later version)
hash/_info: * License: Public Domain
htable/_info: * License: GPLv2 (or later)
ilog/_info: * License: LGPL (v2 or later)
likely/_info: * License: LGPL (2 or any later version)
str/_info: * License: LGPL (2 or any later version)
tally/_info: * License: LGPL (3 or any later version)
typesafe_cb/_info: * License: LGPL (2 or any later version)

I could fork them and turn them all GPLv3, but that means we can't merge
changes back into CCAN.  That's not very friendly.

We could put a note about the different licenses if you want.

Please, does anyone have a better reason to put a 25 line header on each
file which contains so little useful information?  Better than "that's
what we've always done?".

Thanks,
Rusty.
