... given that `bootstrap' is a ready-to-run script from `gnulib', this should probably discussed with the gnulib people. > The following line in the output of ./bootstrap looks suspicious: > > You may need to add #include directives for the following .h files. > #include <wchar.h> This is OK. What you see here is a list of include files to be used in the source code for the requested gnulib modules (see variable `gnulib_modules' in file `bootstrap.conf'). In particular, `wchar.h' is needed for `wcwidth'. It's *not* related to what you have on your harddisk. Werner
