Another fix is needed, for the 'libtextstyle-optional' module.
Uncovered by the continuous integration.


2021-12-18  Bruno Haible  <bruno@clisp.org>

        libtextstyle-optional: Fix generation of textstyle.h (regr. 2021-12-15).
        * m4/libtextstyle-optional.m4 (gl_LIBTEXTSTYLE_OPTIONAL): Invoke
        gl_CONDITIONAL_HEADER.
