One possible way to fix it is to alter these lines in m4/malloc.m4: [case "$host_os" in # Guess yes on platforms where we know the result. *-gnu* | freebsd* | netbsd* | openbsd* \ | hpux* | solaris* | cygwin* | mingw*) ac_cv_func_malloc_0_nonnull=yes ;; # If we don't know, assume the worst. *) ac_cv_func_malloc_0_nonnull=no ;; esac Is your platform is one where 'yes' is the appropriate answer? If so, what is the value of "$host_os" for you? Perhaps we should change gnulib by adding your platform to the list. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
