That's not a problem (and this is documented -- but to find it,
you have to dig).

The authoritative source for the license is specified in
the module-definition file, gnulib/modules/c-ctype.  It is LGPLv2+.
Besides, our invocation of gnulib-tool (in bootstrap) requires that
any module be compatible with LGPLv2+ via its --lgpl=2 option,
so this is checked automatically.  You may rest assured that
any module I propose for addition has the right copyright.
In addition, when gnulib-tool copies the files into gnulib, it
rewrites the license to be what we require:
