Yes and yes. This started between 5.9.93 and now. Didn't we update our gnulib import since then? > You think that the #include_next line is being executed, right, and > you think this is the case because _GL_ALREADY_INCLUDING_WCHAR_H is > defined? Something like that. And it happens only with some sources that include wchar.h. E.g., mbschr.c compiles fine. > It looks like this is only defined if wchar.h in gnulib indirectly > includes itself.

There was no wcwidth.h in texinfo-5.9.93's gnulib; now there is. So the arrangement of how that declaration is pulled in changed significantly since then. > It could be helpful if you posted the config.log file, and > gnulib/lib/wchar.h as well.
