| Weird... I'm applying this fix. It replaces the iswprint etc. functions.
| The replacement does not consider isprint (since that would make the
| assumption that all locales are unibyte), but only ASCII. Still better than
| the completely broken functions.

Oops - you made the AC_TRY_COMPILE the fourth argument to AC_CACHE_CHECK,
instead of AC_TRY_RUN, breaking this macro on cross-compilation.
| ! AC_TRY_COMPILE([#include <stdlib.h>
| ! #if __GNU_LIBRARY__ == 1

| ! [gl_cv_func_iswcntrl_works=yes],
[gl_cv_func_iswcntrl_works=no])
Oops. You got bitten by the deprecated API. Had you used
AC_COMPILE_IFELSE, where the second argument is the desired
action-if-true, this would work. But in the old AC_TRY_COMPILE,
action-if-true is the third argument.
Fixed as follows:
